Nice Post.
I save it to my cloud account and my mail account
Great.
If you forget or lost these keys, there is no way to recover your keys & passwords as we do like clicking to Forget password.
Hence, it is necessary to save this password offline from where you can get it easily even your system/mobile crashed. I will also say that the best is to save it on Cloud
One Tip On This
Chrome browser users can add this extension and save the keys/password, it will only prompt when needed your confirmation. This can be used anywhere and on any system, just need to sign in Chrome browser and all browser settings will get applied with all your extensions.
Nice Post from you. 
See You Soon.
Thank You.
