What is TOTP authentication and how does it work?

TOTP authentication solutions include physical tokens that rotate six-digit numbers or codes sent via SMS or to an authenticator app on your phone. Utilising TOTP will give your accounts a second factor authentication method (2FA).

What is TOTP (time-based one-time password)?

One of the most common methods is by using a Time-based One-time Password (TOTP). TOTP authentication solutions include physical tokens that rotate six-digit numbers or codes sent via SMS or to an authenticator app on your phone. Utilising TOTP will give your accounts a second factor authentication method (2FA).

What are SMS and TOTP and how do they work?

Both SMS and TOTP add a second factor to the authentication process, keeping user accounts secure against automated brute force attacks –– a form of cyberattack where bots try to leverage stolen credentials to authenticate to an IT resource.

What are the two methods of one-time password (OTP) authentication?

Dive deeper into multi-factor authentication and review two methods of one-time password (OTP) - hash-based (HOTP) & time-based (TOTP) one-time passwords. One-Time Password (OTP) Authentication Methods You Should Know – HOTP + TOTP

Is TOTP more secure than SMS?

Despite its potential weaknesses, TOTP 2FA is more secure than SMS, while also being just as lightweight and easy to access.

Is TOTP more secure than HOTP?

TOTPs are considered an evolved form of HOTPs— they imply more security because of having an extra factor to meet the algorithm conditions.

What is difference between OTP and TOTP?

Time-based One-time Password (TOTP) is a time-based OTP. The seed for TOTP is static, just like in HOTP, but the moving factor in a TOTP is time-based rather than counter-based. The amount of time in which each password is valid is called a timestep. As a rule, timesteps tend to be 30 seconds or 60 seconds in length.

What is HOTP and TOTP?

HOTP stands for HMAC-based One-Time Password and is the original standard that TOTP was based on. Both methods use a secret key as one of the inputs, but while TOTP uses the system time for the other input, HOTP uses a counter, which increments with each new validation.

Is TOTP safe?

TOTP Authentication Implementations Passwords are not secure. But you can combine a standard password with a Time-Based One-Time Password (TOTP). Such a combination is Two-Factor Authentication (2FA) and can be used to safely authenticate to your accounts, VPNs, and applications.

Is Google Authenticator TOTP or HOTP?

Google Authenticator is a software-based authenticator by Google that implements two-step verification services using the Time-based One-time Password Algorithm (TOTP; specified in RFC 6238) and HMAC-based One-time Password algorithm (HOTP; specified in RFC 4226), for authenticating users of software applications.

What is TOTP example?

A time-based one-time password (TOTP) is a temporary passcode generated by an algorithm that uses the current time of day as one of its authentication factors. Time-based one-time passwords are commonly used for two-factor authentication and have seen growing adoption by cloud application providers.

How do I create a TOTP?

What is a TOTP key?

Time-based One-Time Password (TOTP) is a single-use passcode typically used for authenticating users. The user is assigned a TOPT generator delivered as a hardware key fob or software token.

What is TOTP and how it can be generated?

TOTP is an instance of a hash-based message verification code. Your mobile device's time must be in sync with the Indian Standard Time zone or IST time-zone and this is the main prerequisite for generating a TOTP in aadhaar. The TOTP in aadhaar is produced in mobile application mAadhaar.

How does TOTP token work?

When the client logs into the protected website, they have to confirm they possess the secret key. So their TOTP token merges the seed and the current timestep and generates a HASH value by running a predetermined HASH function. This value essentially is the OTP code the user sees on the token.

What does OTP mean?

service provider to refer to the website service provider (e.g., Google, Facebook, Twitter, etc.); OTP to mean one-time password; and. trusted device to refer to any device capable of running an authenticator app that can generate OTPs according to the TOTP specification, such as Google Authenticator.

Is TOTP 2FA more secure than SMS 2FA?

In addition to the usability benefits, TOTP 2FA is significantly, dramatically more secure than SMS 2FA. If you take a peek back at the SMS 2FA article, you’ll notice that a huge source of vulnerabilities came from the phone company and network.

Does TOTP 2FA have security flaws?

Eliminating those has huge security benefits: no more social engineering people at the phone company, no more insider threats at the phone company, no more SS7 attacks on the phone network redirecting your texts, etc. However, TOTP 2FA does have its own flaws.

What is TOTP?

TOTP or Time Based One Time Password is the most common form of Two-Factor Authentication in today’s time. In this, unique passwords consisting of numbers are generated through standardized algorithms. These time-based passwords are available offline and provide user-friendly, increased security when used as a second factor.

How Is TOTP 2FA Better than SMS 2FA?

For the authentication process and to keep the accounts of users secure and reliable, both SMS and TOTP use a two-factor authentication system. It helps to protect your account from automated cyberattacks.

Potential TOTP 2FA Risks

TOTP has some design shortcomings despite being the secure and reliable two-factor authentication method. The code of TOTP depends on the shared secret stored by the app and the server it stays connected to. In case the hacker manages to recover the shared secret, they can generate the codes according to their will.

How often do you have to renew your password?

Password policies. To ensure good password management, companies are forcing users to renew their password every 3 months or so. This usually results in people reusing older iterations of their passwords or using the month/year in their passwords. Password management practices are not very secure!

Is password management secure?

Password management practices are not very secure! Another option is to use a password manager. This will make sure that your passwords are better secured and not that easily accessible. But it’s just another way to write the password down, a current way to game the system and make it easier to access your accounts.

Is it better to use a long password or a complex password?

While it is better to use long passphrases than complex passwords, there are additional ways to enhance the security of accounts. One of the most common methods is by using a Time-based One-time Password (TOTP).

Can you use a passphrase instead of a password?

A passphrase instead? A better option might be to use a password with many characters (be it letters, numbers or special characters). With longer passwords, even by stapling words after each other to create a sentence, you create a difficult password to decrypt but is easier to remember.

What is TOTP password?

TOTP stands for Time-based One-Time Passwords and is a common form of two factor authentication (2FA). Unique numeric passwords are generated with a standardized algorithm that uses the current time as an input. The time-based passwords are available offline and provide user friendly, increased account security when used as a second factor.

What is TOTP authentication?

TOTP is also known as app based authentication, software tokens, or soft tokens. Authentication apps like Authy and Google Authenticator support the TOTP standard. Twilio's Verify API offers support for TOTP authentication in addition to SMS, voice, email, and push channels.

What is HOTP in TOTP?

HOTP stands for HMAC -based One-Time Password and is the original standard that TOTP was based on. Both methods use a secret key as one of the inputs, but while TOTP uses the system time for the other input, HOTP uses a counter, which increments with each new validation. With HOTP, both parties increment the counter and use ...

What is TOTP in 2FA?

One-time passwords, including TOTP, are a common possession or "something you have" factor and help increase the security of your users accounts. A recent study about the usability of 2FA methods found that TOTP had the highest usability score ...

What is TOTP algorithm?

The TOTP algorithm follows an open standard documented in RFC 6238. The inputs include a shared secret key and the system time. The diagram below shows how the two parties can separately calculate the passcode without internet connectivity.

Is TOTP stronger than SMS?

TOTP has stronger proof of possession than SMS, which can be legitimately accessed via multiple devices and may be susceptible to SIM swap attacks. Most customers end up implementing multiple forms of 2FA so their users can choose the channel that works best for them.

Can you access TOTP while offline?

Therefore a user can access TOTP via an app like Authy while offline. TOTP's offline support is ideal for users who might need to access their authentication while traveling abroad, on a plane, in a remote area, or otherwise without network connectivity.

What is an OTP password?

An OTP is like a password but it can only be used once, thus it stands for one-time password. It is often used in combination with a regular password as an additional authentication mechanism providing extra security. OTPs are exactly what they sound like: one and done. Once you’ve used that password once, it’s dumped, ...

How long is a password valid?

The amount of time in which each password is valid is called a timestep. As a rule, timesteps tend to be 30 seconds or 60 seconds in length. If you haven’t used your password within that window, it will no longer be valid, and you’ll need to request a new one to gain access to your application.

Is SMS based MFA better than SMS?

While SMS-based MFAs might be better than no M FA at all, they’re a lot less secure than having an authenticator app on your phone or using a key fob code generator.

Is HOTP more secure than TOTP?

While both are far more secure than not using MFA at all, there are limitations and advantages to both HOTP and TOTP. TOTP (the newer of the two technologies) is easy to use and implement, but the time-based element does have a potential for time-drift (the lag between the password creation and use). If the user doesn’t enter the TOTP right away, there’s a chance it will expire before they do. So the server has to account for that and make it easy for the user to try again without automatically locking them out.

What is a HOTP and TOTP?

HOTP and TOTP are the two main standards for One-Time Password but what do they mean from a security perspective, and why would you choose one over the other? In both HOTP and TOTP the token (ie, the OTP generator) generates a numeric code, usually 6 or 8 digits.

What is the difference between OTP and HOTP?

Comparison. Both OTP schemes offer single-use codes but the key difference is that in HOTP a given OTP is valid until it is used , or until a subsequent OTP is used. In HOTP there are a number of valid "next OTP" codes. This is because the button on the token can be pressed, thus incrementing the counter on the token, ...

What is an event based OTP?

Event-based OTP (also called HOTP meaning HMAC-based One-Time Password) is the original One-Time Password algorithm and relies on two pieces of information. The first is the secret key, called the "seed", which is known only by the token and the server that validates submitted OTP codes.

What is HOTP validation window?

Specifically, they will accept an OTP that is generated by a counter that is within a set number of increments from the previous counter value stored on the server. This is range is referred to as the validation window.

Why are TOTPs considered an evolved form of HOTPs?

TOTPs are considered an evolved form of HOTPs— they imply more security because of having an extra factor to meet the algorithm conditions. ✅ Hash-based one-time passwords can be more user friendly.

What is OTP authentication?

OTP stands for "one-time password" and it is frequently used as an additional verification factor in multi-factor authentic ation systems.

How long does a TOTP timestep last?

The duration of a timestep for a TOTP usually lasts between 30 and 180 seconds, but you can personalize this time lapse. Hence, if the user doesn't enter the one-time password in the set amount of time, the code won't be valid anymore.

Can a third user hack a one time password?

In the unlikely event that a third user would take over the user’s device and hack the one-time code, this can only be used once. One-time passwords are frequently used as a complementary authentication factor in multi-factor authentication processes, but it can also be the sole method to authenticate a user.

How to intercept a TOTP code?

The most basic way to intercept SMS codes is by either swapping out the victim’s SIM card or impersonating the victim and ordering a copy of their SIM card to be sent to a different address. Or, a hacker may be able to target a specific user’s phone and steal it.

How often should TOTP codes be refreshed?

A good practice for organizations is to set the codes to refresh every 30 to 60 seconds, making the codes harder to use if stolen. If a bad actor were to obtain a TOTP code, for example, they would need to act in real time to use it before it expires. TOTP codes are more difficult to intercept than SMS to begin with.

What is SMS authentication?

SMS is a common delivery method for two-factor authentication (2FA) –– or multi-factor authentication (MFA). It’s quick, easy to access, doesn’t burden systems or other resources, and keeps user accounts more secure than those without any form of 2FA in place.

How long does SMS 2FA last?

However, SMS 2FA uses a static code that either expires after it’s been used, or if it hasn’t been used in some time period — say, 10 minutes after being sent. If a bad actor were to obtain that code before a user submits it, they could easily access the account in question.

Is TOTP more secure than SMS?

Although TOTP is more secure than SMS 2FA, it has some shortcomings in its design. For instance, TOTP codes rely on a shared secret, or “seed,” stored by both the app and the server it’s connected to. If a bad actor manages to recover the shared secret, they can generate new codes at will. Because of this, provided they have compromised a user’s credentials along with their “seed,” they can access the user’s IT resources.
