All you have to do now is select the user account you want to reset, enter a new password or leave it blank and click Save. Then just simply restart the computer from the Apple menu and login with. Actually, you can use this feature to reset the password for any user account type, including a standard account, managed account, or sharing account. In order to use your Apple ID to reset an account's password, the Apple ID must be associated with that account. Security info, your backup email or phone number, lets us contact you if there's something wrong with your account. This is important if you forget your password or someone else tries to use your account.
My Password Security
The biggest risk when setting a password is when you re-use a password across sites and services. If you do this, you’re multiplying the risk of a breach at one of those services, allowing a cracker to try your account name and password from the breached service at other sites. If any match, they’ve now hijacked your account there, too. A unique password at every site is the goal. And Apple added an alert in iOS 12 and macOS 10.14 Mojave that will help you towards that.
IDG This warning tries to push you towards a slightly lower level of risk online. Don’t worry: I’ve changed all those passwords.

In iOS 12, you find it in Settings > Passwords & Accounts > Website & App Passwords. In macOS Mojave, it’s located in Safari, in Preferences > Passwords. Any stored password that’s shared among multiple stored logins has a caution sign (black in iOS, the appropriate yellow in Mojave). Tap the entry in iOS or click the caution sign in Mojave’s Safari, and you get a more complete explanation. You can also tap or click the proffered link to change the password. Apple will take you either to the account management page on sites that use a URL Apple knows or to the homepage, from which you can navigate.
Wherever the site lets you change the password, Safari will autofill the old password and suggest a new, strong one that it retains for you and, with iCloud Keychain enabled, sync that password among all your devices. In iOS, you can’t view all your reused passwords at once, but have to scroll to find them. Mojave, however, lets you sort by the caution sign in Safari’s preferences: click the empty space at the top of the caution column and it clusters all the reused passwords together, if you want to change them all at once. As another safeguard, sign up at, a free service offered by an Australian security researcher and trainer that alerts you whenever a new password breach appears that contains your email address. (The site’s operator doesn’t have your password or know if it’s been cracked.)
