Owners of a MacBook Pro with Touch Bar may occasionally run into an issue where the Touch Bar gets stuck on a “Touch ID to Log In” screen, often with a Safari icon, displaying even if Safari is not the foremost app on the Mac.
Tapping on the ‘Cancel’ button on the Touch Bar doesn’t do anything, and the “Touch ID to Log In” message persists on the Touch Bar. You can attempt to put your finger on the Touch ID reader to login (to whatever mystery site or login is requesting the login… if you trust not knowing), but even that doesn’t dispel the message from being stuck on the Touch Bar.
There’s a pretty simple remedy to this issue, and you can fix a stuck “Touch ID to Log In” message on a Mac Touch Bar relatively easily with just a few steps.
