After resetting Touch ID, you’ll need to re-register your fingerprints. Go to Settings > Touch ID & Passcode, and then tap on “Add a Fingerprint”. Follow the on-screen instructions to register your fingerprints again. Make sure to register multiple fingerprints for added convenience and security.
Can I use Touch ID with a screen protector or case?
Most screen protectors and cases are designed to work with Touch ID. However, some screen protectors or cases may interfere with the Touch ID functionality. This is usually due to the thickness or material of the screen protector or case, which can block the Touch ID sensor’s ability to read fingerprints.
If you’re using a screen protector or case and experiencing Touch ID issues, try removing it and see if Touch ID works without it. If it does, you may need to consider a different screen protector or case that is designed to work with Touch ID.
