This is important for reasons others have already mentioned. My current password manager has a field pre-filled, for each entry, with a default set of special characters, but I can change it to exactly what each site allows.

The idea of more options is important. May I add that the request "to exclude Special Characters" is vital to me. Most of my important sites (banks, insurance, etc) accept only a subset of special characters. Always several that Proton has that cannot be in their password. Sometimes a few Proton doesn't allow. That makes the password generator challenging!

It's be really cool if these options could be saved per "card," e.g., per website. That's in the nice to have. The must-have is the option.

And also more option for generate password like in keepass.

Very huge my bank does not allow ! or @ to be used within a password for some arbitrary reason

I have many passwords in another password manager that use an extended set of special characters. I wonder what happens if I try importing them. Overall, no consensus about what special characters should be part of the family; I'd vote for anything that can be found on a regular keyboard.

mSecure allows you to decide for each entry the pw length and whether to:
- include special characters
- exclude special characters
- only use these characters: <user choice>

Some password requirements only allow specific special characters.

It frustrates me when sites limit what special characters you can use, and honestly it tells me they are doing something jankey under the hood, that and imposing a maximum character limit of 18-20 when that should be the minimum these days.
I've started where i can just refusing to do business with companies that do both these together. If it is just one or the other i'll comapin, but both they're likely not prioritizing security

A space is also a valid character for passwords in several apps that I use whenever I can since it's not expected and would be a lot harder to guess.

That is a good point! But I dont know if I would use emojis, but its a nice extra. I would also love to be able to create a 100 long character password. At the moment it's only possible to create a 64 long character password. :(
For example: 1 Password has this feature.

This would be very helpful

And a cloud sync of these password preferences, e.g. if 99% of the community say "can't have a * character" then fetch and set this preference by default for everyone else. Like how Waze handles roadworks: if enough people say it's present then it's present.

Agree; this feature would significantly improve the usability of Proton Pass on websites that have restrictive password requirements.

Who uses emoji in passwords? Come on, be serious. It's not a priority.

This is super important, running into this issue quite a bit.

Agree; this feature would significantly improve the usability of Proton Pass on websites that have restrictive password requirements.

For example, Lufthansa requires you to use a special character, but only accepts these characters: !"$%&'()*+,-/:;#<>?_@\

Sites that put limits on the type or number of specials should be fined. The "guess which special we want!" game is tiring and reduces the security of the password. Customizing the generator would be gold - please do this!

Two special character toggles should suffice. One for the standard !@#$%^&*, and one that includes all the others such as {}:"<>?[];',./.

It would be very beneficial if the password generator had additional customization options such as the ability to set a minimum number of special characters, numbers, or letters that will be included in the username. Additionally, having the ability to select capitalized vs uncapitalized letters and to select which special characters are included in the password. An example of the implementation for this would be a checkbox next to "Uppercase", "Lowercase", "+", "#", "@", etc...
