Even made a little to tool to help out when the browser extension did not work: https://ph.leftium.com/
Unfortunately I ended up with multiple "master" passwords:
- When forced to change the password for a site.
- Or when your master password resulted in a hashed password that failed a site's password requirements.
These days I just use a password manager (Enpass). Whenever possible, I use "pronounceable" passwords because when auto-insert is not possible it's easier to type a series of words than random characters/symbols. Especially on mobile.
