One-Time Passwords


Use Verifyr for easy, secure sign-ins for all your online accounts using multi-factor authentication (2FA).


Getting started with multi-factor authentication

Multi factor authentication (MFA) provides a second layer of security. When enabled, during login after entering your password, you’ll be asked for an additional way to prove it’s really you. Enter the one-time password (OTP) generated by the Verifry App. The OTP codes have a 30 second timer counting down. This timer is so you never have to use the same time-based one-time password (TOTP) twice and you don’t have to remember the number. The OTP doesn’t require you to be connected to a network, and it won’t drain your battery. You can add multiple accounts to your app, including accounts like Facebook, Amazon, Dropbox, Google, LinkedIn, GitHub, and more.

TOTP

Verifyr generates one-time passwords on a time based solution, this is called TOPT and it's the most common algorithm used on services. 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 one time password within that window, it will no longer be valid, and you’ll need to request a new one to gain access to your service which request a two factor authentication.

HOTP

You can also use HOTP one-time passwords with Verifyr. The "H" in HOTP stands for Hash-based Message Authentication Code (HMAC). Each time the HOTP is requested and validated, the moving factor is incremented based on a counter.
