Generate all of my passwords with it and keep everything in a secured and encrypted vault kept secure by my one master password.
No longer need to remember passwords and I now have a unique password for every website that I am signed up on whilst activating two factor authentication wherever possible.
As I use SSO with either Google, GitHub or Facebook where possible I add it to the names of logins as such:
(G) stands for Google. Alternatively it could be
(H) for GitHub and
(F) for Facebook. Facebook is good for times when a service does need to hook into my friend circle (Spotify is good example of it).
