With Arengu, you can do so in minutes and with no coding skills. Plus, implementing OTPs in your process is as easy as adding the proper actions to the flow of your onboarding form. The probabilities of fraud or failure when using one-time passwords in 2FA is positively low. Using one-time passwords is a way of reinforcing forms based on passwords, verifying the user's phone number or email account. Whatever type of one-time code you use, you can be sure that multi-step authentication processes are an efficient way of onboarding users. Implementing HOTPs or TOPs in your auth systems In this case, the user will need to ask for an extra code. If the user lacks any of them, the code won't arrive on the user's device and they will be incapable of entering the code and verifying their identity. In both cases, the sending of the one-time codes depends on external factors, such as broadband coverage (for SMS and calls) and internet connection (for email or messaging apps). Since they are not limited by the timesteps and can enter the code whenever they want to. ✅ Hash-based one-time passwords can be more user friendly. TOTPs are considered an evolved form of HOTPs- they imply more security because of having an extra factor to meet the algorithm conditions. The fact of adding an extra factor that needs to be met increases the security of the code. ✅ Time-based one-time passwords tend to be more secure, because they're only valid in a certain period of time, which adds a certain layer of security. Which one is better? Advantages of each OTP With TOTPs the moving factor is their limitation in time, while with HOTPs the moving factor is the counter that is activated with each event - a following code request. Both have a moving factor that changes them. The moving factor is the main difference between these two types of OTPs. Hence, if the user doesn't enter the one-time password in the set amount of time, the code won't be valid anymore. The duration of a timestep for a TOTP usually lasts between 30 and 180 seconds, but you can personalize this time lapse. TOPT stands for "time-based one-time password".Īs opposed to the previous type, these OTPs base their functioning on time sequences called timesteps. TOTPs are one-time passwords based on time. HOTPs aren’t usually based on time, instead they are valid until the following code is requested by the user. This token is sent to the user and is based on a hash algorithm, hence the name "hash-based one-time passwords". This kind of OTP consists of the generation of a token that only the user and the server can know. The generation of this type of code is based on a counter, that is activated and incremented with each event. HOTP stands for "hash-based one-time password", therefore it is based on hash-based message authentication codes. HOTPs are one-time codes based on events. These authentication codes can be based on events (HOTP) or on time (TOTP). 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. 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. This makes OTPs a pretty secure system to recover accounts or add an extra layer of security to them. Unlike passwords, users can only use one-time codes once. It is usually compounded by 4 to 6 characters that the user has to enter in order to verify their identity. But what are HOTPs and TOTPs? Do you want to know the difference between them? Which one is more recommended? What is an OTP?Ī one-time password or OTP is a unique code that is sent to a user, normally to their email or phone. In general terms, two different types of OTPs can be distinguished - HOTPs and TOTPs. You probably used them as a user, but when it comes to implementing them in your own verification system, what kind of OTP is more suitable? OTP stands for "one-time password" and it is frequently used as an additional verification factor in multi-factor authentication systems. In order to protect users’ from password theft and account takeovers, multi-factor authentication with one-time passwords is heavily used. Protecting users’ identity online has become one of the most important challenges in the online world.
