Work with iCloud Keychain
4 Add website credentials
The quick way to add usernames and passwords to your keychain is Safari > Preferences > Passwords, by entering them manually – but take care to type correctly. Click Add, enter a site address and your username and password for it.
7 Edit keychain on a Mac
Say you change a password, perhaps because a site suffers a security breach. Follow the site’s reset steps, then sign in; Safari asks to update your keychain. Or, preemptively click the password in Safari’s Passwords prefs to edit it directly.
10View keychain on iOS
In iOS 11, apps can use keychain. If an app hasn’t been updated for this, go to Settings > Accounts & Passwords > App & Website Passwords, hold a finger on an item, pick Copy Username or Copy Password, switch to the app, then paste.
5 Save at sign in
Instead of, or as well as, the previous step’s method, take advantage of Safari’s offer to save details when you first sign in to a site. Also, when creating an account and the focus reaches the password field, Safari suggests one; click it to accept it.
8 Edit keychain on a Mac
When you visit the Passwords tab, you’ll need to enter your password (or use Touch ID) to view items. Each is only readable when its row is selected; make sure you don’t leave this tab open and unlocked for all your family to read!
11 Remove password
If you delete an account, remove its details from your keychain on one device and they’ll go from others, too. On a Mac, select it in Safari’s Passwords list and click Remove. On iOS, swipe left on it in the passwords list and tap Delete.
6 Save at account setup
Alternatively, click the icon at the right of the field for another suggestion. Your credentials are saved to iCloud Keychain and are available on all devices you connect to it. Some sites – banks, say – can request for details not to be saved.
9 AutoFill on iOS
If Settings > Safari > AutoFill > Names and Passwords is on and you visit a signin page, saved credentials for the site are shown above the keyboard; tap one to fill out the form, or tap Passwords to choose from other saved account details.
12 Add bank card details
In Safari > AutoFill, click Edit next to Credit Cards. Click Add and fill out the details. For security reasons, CVV codes aren’t stored; they must be memorised. To edit a detail, click it; altering the long card number requires your password.
