Solved! Go to Solution.
Go to Settings > Apps > Search for Samsung Pass. Clear the data of that and Autofill for Samsung Pass.
In the event that two Samsung Pass applications show up, just clear both of them.
I can certainly understand how frustrating using features for the first time can be. Samsung Pass requires a secure lock like your password, PIN, or Pattern in order to use its features. This is a security measure in place to protect your saved passwords. Unfortunately this requirement/feature cannot be deleted or disabled. I apologize for the inconvenience this may cause.
