1Password is the best password manager for the Mac. (It synchronizes with the iPhone and iPad too, so your passwords are always up to date.) Most people access their passwords by clicking the 1Password button on the toolbar in Safari, Firefox, or Chrome, or they open 1Password in the Dock or from the menu bar, but those are slow ways to go.
The fast way: Command-\ (⌘-\)
This pops open the 1Password “Unlock” box if 1Password is locked, and after you enter your master password and hit Return, 1Password automatically pops in the username and password you need for the website you’re on.
If 1Password is already unlocked, ⌘-\ fills in the username and password without you doing anything more.
Try it once and you’ll be hooked.
