How do I merge duplicates in Apple Password on my MacBook Air?

Hi there!

In Apple Passwords, you might see several entries for the same site that have different user credentials. For example, you might see two listed for Apple if you use two Apple Accounts. To remove listed passwords you don't use, you can either select them, choose Edit, then Delete, or control-click them and choose Delete.

Regrettably, there isn't a way to merge passwords since each password entry in Passwords is unique to a specific site and username/password combination.

Hope this helps!
