Hello and welcome to the community!
I don’t know what went wrong, but this sounds to me like BW captured the wrong value, possibly because the website did something “non-standard” on the password. So what you did didn’t work on one website, but worked on another website.
Having BW capturing the credentials from the form is not always a sure thing, so it’s usually recommended that:
Adding a new account:
- Goto the registration page
- Open BW side-bar; on FF, its Shift-Alt-Y
- Click the + button
- Generate user name (or email)
- Generate a random password (do this for security)
- Click save
- Ctrl-Shift-L to fill in the info in the registration form
You will have to fiddle with this with sites that use both username/email. But the gist is, save your registration info in Bitwarden first, and have Bitwarden fill in the registration form for you.
Changing the password is slightly more tricky. This is what I do, but maybe others will have something simpler:
- Goto the password change page
- Open the sidebar
- Drag-and-drop the old password from the sidebar into the current password field
- Generate a new random password in Bitwarden and save.
- Drag-and-drop the new password from the sidebar into the new password fields.
Remember that Bitwarden remembers you last 5 password plus the current one. Look at the bottom of the entry and you’ll see “Password history.” Clicking on the number will show the previous passwords just in case you need them.
