Free bitwaden for the students ??
It won’t be economically viable, Bitwarden is already very cheap compared to other PW managers. Also opens up possible abuse for people who buy a student email and pretend to be students.
Free bitwarden for the students? There’s a free version of bitwarden for all, not only the students and it is good enough for average users. Besides, the 1$/month families account is insanely cheap comparing to other password managers.
Don’t be a cheap and pay the relatively low price for the full version. And if you can’t or won’t pay for it, use the free version without the premiums. In my opinion this is more than enough for a student.
