Free Client Logins
If some of your clients require read-only access to their account credentials stored in Passwordstate, you can simply "tag" their account to a specific Site Location, and you will not consume one of your standard Passwordstate Client Access licenses.
When applying permissions to Password List and Folders for clients, only the relevant accounts are visible for each Site Location - so you cannot make the mistake of granting one client's passwords to another client.
And of course, you can select any one of the many different two-factor authentication options for your clients, or simply give them a Local Login account - they can use different authentication methods compared to your IT Staff.
