I'm currently using Bitwarden as my open source password management.
I'm getting problems on login when using the bitwarden chrome extension (or brave actually), but I think the problem is probably extensible to other password managers (like 1Password or LastPass - which I have not tested).
The issue can be described as:
Note that I have disabled my chrome/brave to save password on this site
On the login page of iDempiere I choose the bitwarden entry I want to use to fill user/pass
The user and password fields are filled
Click OK to login and the system shows (in the best scenario) the error "Invalid User ID or Password"
Debugging I notice that the userId is still empty in memory, although it is filled and showing a value in the UI
In the worst scenario, suppose you have two entries with different username and same password (for example SuperUser and System that are sharing the same password System) - it is possible to login inadvertently with the wrong user - because it's showing a user in the UI and in memory is really working and login in with a different user than seen.
