Try a Password Manager

Password Managers (PMs) enable you to save all your passwords as one master password on your Mac. They include:
1Password, Keeper, Blur, Stickypassword, PasswordBoss, Lastpass, Dashlane, LogmeOnce, Roboform, Zohovault, Truekey and EnPass

The last,  Enpass does not need a subscription like the others. Its use with less than 20 passwords is free.  For more passwords you need the premium version, $9.99 for one device.

Search your Apple Mac

 

Have you ever lost a document or image on your Mac?  Apple’s Spotlight Search is one of the more underused tools available and can help with this problem. To open Spotlight Search, press <cmd> and the space bar, or click the magnifying glass icon, top right of the screen. On more recent versions of Mac OX, you can drag the box around.
