The latest version of iOS, version 15.4, finally brings support for Face ID with masks.

Despite the security benefits of Face ID, the pandemic has shown a spotlight on its biggest limitation: using it while wearing a mask. Apple has finally brought support for unlocking an iPhone via Face ID, even with a mask on.

To enable the feature:

• Open Settings and tap Face ID and Passcode.
• Toggle the Face ID with a Mask button on.
• Follow the onscreen prompts to set up a facial scan with your mask on.
