From the Preferences menu, click the Keychain Access option. If you’d like to sync your keychain passwords, double-click the keychain item you’d like to synchronize. Then, click on the password box, type the password, and click OK. Alternatively, right-click the keychain login item and choose Copy password.

Turn off keychain
If you’re a Mac user and you want to make sure you don’t lose your passwords, you may want to turn off the keychain on your computer. It’s an easy way to prevent someone from using your passwords. The keychain is used for many other things besides password management. You can even lock it, if you want.
If you can’t remember the password to log into Keychain, you can try typing ls in the Terminal window. This command will show you a long string of random numbers in your Keychains directory. You can then type rm -rf to delete these folders. You’ll need the full name of the folder to complete this. After this, restart your Mac OS.
Another way to turn off the keychain on a mac is to disable the feature for it. If you’re getting the “login” message, this feature may be causing your problems. To turn off the feature, go to System Preferences > iCloud and turn off the option.
Delete old passwords
If you use Apple computers, you have probably come across a program called Keychain Access. This app helps you manage your passwords, account numbers, and other personal data and syncs them across all your devices. Changing the password of a website or account will require you to update this information, so it is important that you delete old passwords and add new ones. If you don’t do this, you will have trouble logging in to websites or services that use the old password.
If you don’t want to use these passwords, you can delete them from the Keychain on your Mac by using the method outlined below. To delete individual passwords, open Keychain Access, and control-click the item you want to delete. Alternatively, you can use the search bar to find the old passwords and delete them. You can also select multiple login entries at a time by holding down the Command key.
Some passwords are associated with multiple websites. For example, a university account may require you to log in to multiple pages. Once you’ve deleted the site that you used to log into the account, you can delete that password from the Keychain.
Repair keychain
If you’re having problems with multiple account password entries on your keychain, there are some things that you can do to fix the problem. First, you need to shut off the iCloud Keychain. To do this, open Keychain Access in the Utility folder in the top-level Applications folder. Note that this application is locked by Sierra SIP. When you open it, you’ll see your login keychain, which is used for authentication each time you log in to your Mac.
Once you’ve done that, you can reboot your Mac. When the system restarts, a new folder will appear in the Keychains folder. It will have a name similar to 4B29A0BB. If this isn’t the problem, you can try to restore the Keychain by following these steps.
You can also try restoring the Keychain from iCloud or a backup. However, you should note that these methods don’t work for all applications. If you can’t access the app’s keychain, there is a possibility that you won’t be able to use it at all. This can be stressful, but you don’t have to lose your precious data. Luckily, there are three ways you can repair a keychain on Mac.
