Most of the time when your entering in the master password, there is a key cut off limit, so even tho your entering the whole password in your mind, the master login is only accepting the max number of input variables, example:
You type Password1234 to set the app up
The master password app only allows 11 characters so it saves Password123
You try to login a locked app with Password1234
it denies because it allows 25 characters not 11 and its expecting Password123
You go into the master password app and still type Pasword1234
but it only reads the max character limit which was Password123
and it allows you to login
So your technically typing in the wrong saved password on both ends its just the app allows you to enter because it stops accepting characters before you stop typing which inevitably is the password that got saved originally.
@tom_white That may be the case with other services. The master password in Bitwarden can be - as far as I know - theoretically up to 256 characters (at least thatās the limit until the hash getās cut off).
This is not accurate. Iām not sure whether there is any character limit on Bitwardenās master password (the new password input field does not specify a maxlength attribute, so presumably up to 524,288 characters can be input). Iāve tested it with a 1025-character master password ending in an exclamation mark (!), and found that changing the 1025th character from ! to ? on the login form causes the login to fail, whereas leaving the 1025th character as ! on the login form causes the login to succeed:
