Strong Password Generator
When you need a new password for a site, such as on a Change Password page, you can open the Strong Password Generator by selecting it from the 1Password toolbar icon menu:
The Strong Password Generator helps you create very strong passwords by randomly creating a unique password for you each time it is used.
Once you have a password you like, clicking the Fill button will automatically copy the new password into every blank password field of the current page.
Password History
If you ever forget to save a newly generated password, don’t worry! 1Password will automatically keep track of all your generated passwords for you in the Password History section.
If you wish, you can delete these history items when they are no longer needed.
