I’d really like to see Bitwarden remember the particular password generator settings you use for each site. And that includes allowing you to specify a custom set of special characters. Sites vary in all the various requirements but many don’t clearly tell you what those requirements are.
I always want to create the most maximally robust passwords possible, so not knowing the maximum requirements is an obstacle, and having to configure the generator each time once I do know them is cumbersome.
This feature is important because it’s good practice to change your passwords on some relatively frequent basis, and thus the process for doing that should be made as easy as possible, or you won’t bother doing it.
