Use Touch ID to unlock your Mac: part 2
After you set up Touch ID, you can use it to unlock your Mac. Wake up your Mac by opening the lid, pressing a key, or tapping the trackpad. Then place your finger lightly on Touch ID to log in.
Note that you must type your password to log in after you start up, restart, or log out of your Mac. When you're logged in, you can quickly authenticate with Touch ID whenever you're asked for your password.
You can also use Touch ID to unlock these features on your Mac:
Password-protected Notes
The Passwords section in Safari preferences
System Preferences
Note that you must type your password rather than use Touch ID to unlock the Security & Privacy pane and the Users & Groups pane (if you have FileVault turned on).
If multiple users set up Touch ID and log in to the same Mac, they can use Touch ID to switch accounts. Just press Touch ID, and your MacBook Pro switches to the logged-in user account associated with the fingerprint.
Make iTunes Store, App Store, and iBooks Store purchases with Touch ID
Use Touch ID instead of your Apple ID password to make purchases on your Mac:
Open the iTunes Store, App Store, or iBooks Store.
Click the buy button for something you want to purchase. A Touch ID prompt appears.
Place your finger on Touch ID to complete the purchase.
You might be prompted to enter your password on your first purchase or if you've made changes to the fingerprints that you've enrolled in Touch ID.
Use Touch ID for Apple Pay
You can make easy, secure, and private purchases on websites using Apple Pay on your Mac. Apple Pay never stores your credit or debit card information and never shares it with the merchant.
Apple Pay is not available in all regions.
Set up Apple Pay
On MacBook Pro models with Touch ID, you’re prompted to configure Apple Pay during setup. Follow the instructions that appear.
If you don’t choose to set up Apple Pay when you first start up, you can set it up later in the Wallet & Apple Pay section of System Preferences. Manage your payment cards there—add or delete cards and make updates to contact information.
Note that you can add payment cards to only one user account on your Mac. If you set up Apple Pay in your main user account and then log in under another account, Touch ID and Apple Pay are unavailable. In this situation, you can use an eligible iPhone or Apple Watch to complete Apple Pay transactions that you begin in Safari on your Mac.
Make a purchase in Safari with Apple Pay
On websites that offer Apple Pay, click the Apple Pay button during checkout. When prompted, confirm the payment by placing your finger lightly on Touch ID.
