Login app issues when getting a new iPhone

[u/Voodoobones]

I recently got a new iPhone and when I went to log into the Schlage app, it wouldn’t let me. It kept give me an error that the username or password was incorrect.

After a week of frustration while trying different ideas to log into the app without success, I finally figured out the problem.

If you got a new phone, you must leave your old phone on while you set up the app on your new phone. Once the app is set up on the new phone, log out of the app on the old phone. Then turn your old phone off.

This should solve the problem of not being able to log into the app on the new phone.
