I also have a number of accounts where only certain characters from the password are required. Something I do that works about half the time (depending on how the site is coded) is store individual characters as custom fields. For example:
- My password is EXAMPLE1
- The site is coded so if they want characters 2, 4 and 8, the form fields are named “passwordChar2”, “passwordChar4” and “passwordChar8”. Check this by viewing the page HTML source.
- I store custom fields called “passwordChar1”, “passwordChar2”, etc. with values ‘E’, ‘X’, etc.
- When I’m asked for three characters from my password, I just click the account as normal in Bitwarden and the correct letters are filled in for me. In the example above, X - M - 1.
As I mentioned, this doesn’t work for all websites. Some don’t name the form fields this way, in which case having the character positions visible would be quite handy.
