Really nice extension. It works like a charm.
However, 2FA using Yubikey could be improved. Currently it's checked only once. It could be nice to force 2FA every month for instance or less.

I've been using this add-on for bitwarden in Firefox along with bitwarden free for about nine months now and it works very well to allow me to use unique complicated passwords. I've been gradually changing the passwords for everything I log into and I can get them filled in quickly and easily using the add-in. I've had Firefox as my default browser always and it rarely needs me to retype my master password. That just changed when I temporarily switched to a different default browser(for other reasons) but I'll be switching back to Firefox as default soon. Bitwarden is available on my android phone as well but it's more clunky as I haven't mastered that and don't use it much there. I'm sure I could make better use of it on the phone but I don't really need it there.

In conclusion, bitwarden free is great when used with its Firefox add-on.

Este complemento es imprescindible para mí. Fui usuario de LastPass por muchos años y desde hace más de un año que me cambié me ha ido super bien, no he extrañado mi antiguo gestor para nada. Bitwarden también funciona muy bien en el celular.

The best password manager. Keeps getting better to. Premium Membership is a Great price and so worth it too.

Bitwarden is still great, but after the last update it keeps signing me out and asking for my master password even though I have told it to never lock.
