Setting our own encryption key is fine in case of data breach Works fine with most browsers (chrome on Windows, chromium on Debian, Firefox) I use it as a "second password manager" for most non critical websites. For the others, I will keep using KeePass, but it allows me to save time, so : 5 stars.

It needs some work, but good start. Would like to edit records from the extension panel rather than having to go to the website. I like that it's part of Synology. I trust them more than most of the other companies, at least for now. Looking forward to future updates to the extension.

Seit Wochen funktioniert die Erweiterung in Chrome nicht mehr. Beim Anmelden kommt immer "Dieser Vorgang kann nicht ausgeführt werden. Möglicherweise ist die Netzwerkverbindung instabil oder das System ausgelastet. Bitte versuchen Sie es später erneut." Später ist relativ. Ein händisches Einloggen ist zwar möglich, aber so funktioniert die Auto-Fill-Funktion nicht. Da kann man´s also gleich weg lassen.

1: Opens up a web page where I have to log in to the c2 website every time i want to add a new log in and that is annoying since it gives a pop up with other managers 2: No store option on my Nas server is a big negative point 3: the export csv did not export my credit cards and made a mess of some security notes. 4: I don't understand why there is a generator when I have to create a log in and I have to do point one stated above in my review. lot's to be inproved

The extension is ok and does the job okay :) The UX of entering the encryption key everytime you restart your browser is a little odd... I would love an option for the extension to never lock, or a better solution for entering the key wich is not to open a new tab. ** Update ** This did legit get added to the extension the day after i made this comment - Nice one 🤘

Para ser un servicio gratuito la verdad es que está muy bien. Solo veo un problema y es que no hay forma de guardar la sesión de forma permanente. 4 horas máximo o cada vez abres o cierras el navegador hay que volver a poner las credenciales. Eso es un poco molesto, me gustaría que añadieran la opción de no cerrar nunca la sesión. Se que esta opción es menos segura pero no estaría mal dar la opción al menos. Otros servicios como este ofrecen esa opción en sus extensiones para chrome. Por favor, valoren la posibilidad de añadir esa opción. Gracias.
