TOTP is considered a little more secure because the matchable OTP is only valid for a short window of time while the OTP for HOTP can be valid for an indeterminate amount of time. So, valid OTPs only change after a successful login. The server increments the counter with each successful OTP login. For HOTP a shared counter is used instead of the current time. So, TOTPs are valid only for a short window of time (usually 30 seconds). The server validates the OTP by comparing the all hashes within a certain window of time to the submitted value. For TOTP, your token generator will hash the current time and a shared secret. Time Based (TOTP) and Counter Based (HOTP). There are two different algorithms to choose from for your OTP generators. When a user changes their password they will not be able to re-use any password stored in history. The number of old passwords stored is configurable. This policy saves a history of previous passwords. How many days is a password valid for? After the number of days has expired, the user will be required to change their password. When set, password is not allowed to be the same as the username.ĭefine a Perl regular expression pattern that passwords must match. How many special characters like '?!#%$' are required to be in the password string? How many upper case letters are required to be in the password string? How many lower case letters are required to be in the password string? How many digits are required to be in the password string? There may be more cost effective ways of protecting your password stores. Performance or protecting your passwords stores. You’ll have to weigh what is more important to you. Yes, 20,000 iterations! This is a very intensive CPU operation and with this high of a setting your servers are going to be spending most of their CPU power on hashing. The industry recommended value for this parameter changes every year as CPU power improves. Once they have the database they can reverse engineer user passwords. This hashing is done in the rare case that a hacker gets access to your password database. This value specifies the number of times a password will be hashed before it is stored or verified. The only currently supported algorithm is PBKDF2. Instead they are hashed using standard hashing algorithms before they are stored or validated. Password guess: brute force attacks"ġ8.6.

This is another reason we do NOT recommend MS Authenticator, Authy, or OTP Auth. That is why, if you don't opt for Bitwarden Authenticator, we recommend Aegis Authenticator (Android) and Raivo OTP. I would rather support open source and non big tech providers. This means you are at the mercy of the cloud provider for disaster recovery. MS Authenticator and Authy have one death factor defect: you cannot export your TOTP datastore. I have Microsoft Authenticator but would like to get rid of that as well. The use of a TOTP app that stores the TOTP keys in your password manager is a contentious issue, but that is an aside. Well…for any TOTP except 2FA on Bitwarden itself, yes. Is the TOTP option sufficient to replace my LastPass authenticator app?
