First, there was an issue in my code that caused the Master Password to be required at times instead of Touch ID. I’m happy to say this has been fixed in 1Password 5.1,
... ...
In many cases though, the Master Password prompt was showing up in 5.0 exactly when it should, at least according to our confusing settings—we had Auto-Lock inactivity timeouts for both the Master Password and Touch ID.
In fact, even I had trouble explaining how the “Request After” and “Request Fingerprint After” settings worked together. After explaining (unsuccessfully) to so many people, I knew something had to change.
Starting in 1Password 5.1, there will be a single Auto-Lock timeout that works for both.
Auto-Lock specifies how long 1Password will wait before it locks automatically. To unlock 1Password again, you can use your fingerprint if Touch ID is enabled, otherwise enter your Master Password. Your Master Password will be required after a device restart or when Touch ID authentication fails.
Combined with Lock on Exit, this gives you a great deal of control over when, and how, 1Password locks.
