That way, they provide additional security to the weaker username and password authentication system. There are other methods through which you can get your TOTP:īecause the TOTP is time-based and expires within seconds, hackers don’t have enough time to anticipate your passcodes. For this reason, you always have access to your TOTP so that the server doesn’t need to send an SMS whenever you log in. However, to keep your password secure, we recommend that you use at least 12.

Of course, if you think a 16 digit password is overkill, you may change the password length to 8 characters or any other length. The passcode is created on your end instead of the server’s using the authenticator application. Using our 16 character password generator with special characters, you can easily generate a random password that is secure and strong. However, some TOTPs can last 120 or 240 seconds.

This method is the most widely used, and the codes usually expire after about 30 or 60 seconds. A one-time password is a randomly generated, six-digit number sent to a phone as an SMS or can be generated via a physical or virtual security token. You can also get the codes from an authenticator smartphone application by scanning a QR image. In some models, the TOTP gets to you on your smartphone through an SMS text message. The way it works is that after you have input your account username and password, you’re prompted to add a valid TOTP code into another login interface as proof that you own the account.
