Set up your access

Enter the key you were given and your name. Your device will then ask you to create a passkey — Face ID, Touch ID, a fingerprint, or your screen lock. There is no password to remember, and the key works once.

On an iPhone your passkey syncs through iCloud Keychain; on Android through Google Password Manager. If you use a phone from one and a computer from the other, you can scan a QR code to sign in, or just set up a second passkey on that machine.
