Feature idea: Automatic password rotation
This would probably be no small feat, but I think it would be awesome if 1Password could interface with websites to regularly rotate passwords. For sites that support the service, the desktop app could occasionally contact the website and negotiate the creation of a new random password. Maybe there could be a setting to turn it off for certain sites.
I'm thinking it would require a standard for how the API should work with 1Password. Maybe create some sample libraries, etc.
Maybe it's too aspirational? I think more sites should have two-factor and that might mitigate the need for something like this.
