It's the main feature from Lastpass that I miss and the only reason I would consider going back

This is a critically essential feature for me as I use this class of fill-in item a lot when I am processing web forms for my multiple locations and for members of my family.

100% agree on this.

Came here to ask for this. +3

I migrated to Protonpass and I miss the autocomplete in the forms with personal information, it is the only reason why I would go back to my previous password solution.

Dashlane user for 8 years, I'm testing Proton Pass now.
Auto-fill forms with personal informations is really an important feature I use daily.

This is a must feature

It would be nice to be able to add other types of cards than credit cards. For example, loyalty cards, IDs, passports, etc.

The idea would be that I could have several documents there with the basic data to be able to consult them securely from anywhere, even without autocomplete.

For example:
My country ID, so that I could have the number, expiry date, etc., there.
My private insurance card, so that I have the information I need when I am asked for it.

Currently this information can be put in a secure note, but the idea would be to have a section dedicated to them. Basically they would be like credit cards but all their fields should be modifiable, and let you add custom fields to your needs.

Agreed. I have my grandson's info in a Bitwarden identity with all his information as well as medical insurance info just in case something happens while we have him. I'm also the medical power of attorney for my dad, so I have all his info in an Identity as well. It is very handy and secure.

Totally agree

Would be amazing if the "default identity" could also be configured to use an email alias, so ProtonPass would just automatically fill in your information, generate an alias for you, and you'd be good to go.
