I changed my password recently and now I'm getting locked out. How do I update my saved passwords?
Note: If 'View by' is set to Category, click User Accounts first, and then click Credential Manager.
Select the Windows Credentials option. Locate the set of credentials that you want to update/remove and then expand the corresponding folder.
3. Then click Remove from Vault or Remove (depending upon which version of Windows you are running).
4. Repeat step 3 for any additional sets of credentials
1) Open the Mac Keychain. Click Finder > Go > Utilities > Keychain Access.
2) In Keychain Access, select the Passwords category on the left to review the list of sites and services for which you've saved a password.
3) Right-click the service you want to edit/remove, then left-click Delete. It might take a double tap to activate the right-click.
This only includes passwords saved in Safari, the default Internet browser. iOS 12 help can be found here.
