Very good application. Convenient!!!
Kann nicht mehr ohne. Erleichtert den Arbeitsalltag enorm, nur unter Android ist die App etwas störrisch beim Autofill. Chrome am PC nahezu perfekt.
Très bonne application, je valide.
Très bon produit. Je n'ai aucun regret ! Pas cher non sur l'année et très efficace jusqu'à maintenant.
Todas as funções que se espera de um gerenciador e de forma gratuita.
Просто огонь!!!!!!!!
I've been using Synology C2 Password for a while, and here are my honest thoughts: Pros: The main advantage is that it's completely free, which is great if you're looking for a password manager without extra costs. For basic needs, it does the job. It saves and stores passwords securely, and I haven’t had issues with the actual storage or syncing. Cons: On my Android phone, managing multiple accounts can be a hassle. When there are a lot of saved users for a site, the app doesn’t always show the username in the autofill prompt. I often have to open the app, find the right entry, and then copy the details myself. Autofill doesn’t work everywhere. There are quite a few sites where it either doesn’t show up or just doesn’t fill in the details, so I end up copying and pasting manually more often than I’d like. Another thing I’ve noticed: after restarting my phone, I have to unlock the app again before autofill works in Chrome. It’s not a dealbreaker, but it does slow things down. Overall: It’s a decent password manager, especially since it’s free, but it’s not perfect—particularly on Android. If you just need something simple and don’t mind doing a bit of manual work here and there, it’s worth a try. But if you want flawless autofill on every website and don’t want to jump through extra steps, it might get a little frustrating.
Ich verwende C2 Password seit über einem Jahr und bin äußerst zufrieden damit!
Funktioniert top - besser als jeder andere Gratis-Passwortmanager aus meiner Sicht
tiptop!
