I probably know the symbol en numbers. And i do know a list or pool of passwords i commonly used. But it is very important for me to know when the password manager went from ‘medium’ to ‘strong’.
If it's any help i'm pretty sure that blockchain.com uses
https://github.com/dropbox/zxcvbn for their password strength guesstimation. Not sure if they also did so back in 2014 though.
