When i go to update a password which I do periodically for some apps/websites as an extra security measure, the rules for password generation seem to match whatever the last password I created in 1Password used. This is bad because different apps and websites have different rules about password min/max length, required and prohibited characters, etc.
Unfortunately, some sites don't even make clear what these limits are so it is easy to forget and create a password that won't work. And yes, I have even found websites that both don't tell you the password rules and don't stop you from generating a password they consider invalid! So keeping aware of what is valid for any particular site is important so you don't lock yourself out of a site or create an unnecessary password reset problem that you have to debug.
By default, 1Password should remember the rules used to generate a particular site/app password.
