Multiple Gallery Passwords

I need multiple passwords (in quotes because they can be simple keys stored in a db, no need to use a complex login system…)

to share a single album with multiple clients (i can revoke a "password")

No need to be freeform, they can be generated

see the mockup image i joined (clicking the "add new password" generate a new one)

outside of the app i can manually keep a record of which client I gave which "password" so i can revoke the right "password" when he is no longer my client.

That can replace the actual freeform single password input text

Thanks for your consideration
