Fingerprint password

Okay, so now we have an error message, and probably an iPhone with hardware problem.

If Touch ID isn't working on your iPhone or iPad - Apple Support

Failing that, contact the folks at Apple, discuss your options and alternatives with them: Get Support.

Find your way to the Chat function there.

Touch ID is not a replacement for a password, it’s a mechanism that reduces the frequency when password input is required.

For details on Touch ID and Face ID, see page 11 and following in this Apple document:

https://manuals.info.apple.com/MANUALS/1000/MA1902/en_US/apple-platform-security-guide.pdf

If you haven’t used the phone for more than 12 hours, or if it was powered off or just updated, you must enter the passcode to reënable Touch ID. If you don’t remember the passcode you will have to reset the phone to factory settings. See:If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support

There are many possible reasons.

• Your iPhone does not use Touch ID
• You are using a website that does not respond to Touch ID
• You have performed an action such as powering sown your iPhone which requires your passcode upon restarting

Since you told us absolutely nothing about your scenario, we have no idea what applies in your current situation.

If you mean to unlock your phone if the phone has been restarted, or hasn’t been unlocked for a longish period of time the passcode is required.

If this doesn’t answer your question please provide more details about when your fingerprint doesn’t work.

Thank you for your reply. I had access to fingerprint previously, but for few months I haven’t used my phone and now when I am trying to use it my phone I am unable to access my fingerprint Touch ID and even I have updated the phone. Please help me with solution.

Enter your password once, and see if Touch ID then works.

If Touch ID does not then work...

It is possible that you’ll need to retrain the Touch ID sensor, assuming there’s not an issue with the sensor.

Whether that because of changes to your finger, or due to issues or changes within the sensor.

Now if you’ve forgotten your passcode, that can be reset.

Has your screen been replaced by someone other than Apple? If so that permanently disabled Touch ID.
