    I got bit by a similar issue with another service.

    I could log into the website just fine, but the app kept saying my password was wrong. I reset my password, and when I was generating a new password, I found the root cause:

    At some point, they changed the password policy to have a maximum length of 16 characters. My existing 20 character password worked fine in the website which didn&#x27;t actually enforce a 20-character limit in the password field, but the app was silently truncating the last 4 characters when BitWarden was filling in the field.

    Limiting password length to only 16 characters scares me. It makes me think they&#x27;re not hashing passwords in the back end.
