I have been wanting this feature since I started using Passbolt some three years ago. It would be great to be able to associate multiple URI’s with a password. This is useful for environments where you must authenticate with the same credentials on different services, as is common with LDAP-backed services. The user experience improvement is in that the quickaccess menu would show the password on all web pages that are associated with the password.
For inspiration, look at Bitwarden’s browser extension. It has this feature.
This feature would also be very useful when dealing with a lot of multi-site web solutions, where the username and password are the same, because its the same instance. It just have multiple entry points for the admin panel.
