Keychain Touch Id

Protect a keychain item with Touch ID.

  • Security

When you store a secure item like a password or a private key in the keychain, you dictate the conditions under which that item can be accessed later. Among other things, you can tell keychain services that every time it tries to read the item, it should first seek the user’s permission—for example, by authenticating the user biometrically with Touch ID.
