Good and useful, but it gets stuck trying to do anything else but retrieving login data; for instance trying to delete duplicate entries, same problem trying to add manually login data.
BTW the apps for iPhone/iPad and opening the C2 site do work fine on all the described operations.

Been using this plugin for years and I love it! Super reliable and secure and having the warning system makes keeping on top of yoru security a breeze.

Attendue depuis longtemps, cette appli d'une marque réputée dans la sauvegarde de données ! Tout est bien fait, rien à redire. Confiance en Synology, tout va bien

I switched to C2 after buying a Synology NAS, but also after LastPass changed its usage permissions. Today I have C2 on my Mac Firefox and on my Android phone. Previously I had it on Windows Firefox. I'm a tiny bit terrified of loosing my C2 password, and mainly for that reason I haven't coerced my family into using it. However I am fully satisfied with the service it provides, and it lets me pluck passwords out of thin air even when I'm on holidays.

Works fine. Might not have the bells and whistles of other apps but equally it has not been hacked.

C'est un trés complet et solide gestionnaire des mots de passe.

Sehr gut

Just works - no complaints.
