too many logins and passwords..... it's hard to get into this app...only a single password one time should be needed (like LastPass)

無論是在Chrome或是Edge環境裡,安裝完C2 password的extention後,在extention上永遠都叫我登入,但我即便在其中一個分頁登入C2 password,extention上還是顯示未登入狀態,持續要求我登入。 而且記憶帳號和密碼的功能永遠也啟用不了。 我目前是1password的付費用戶,對這類軟體的應用操作還算熟悉,原本很高興看到有一款國產的密碼管理應用,但實用後卻非常失望。

Сервис хранит пароли в облаке Synology. Отметим что это компания, которая разрабатывает хранилища для ЛИЧНОГО использования. Тем не менее для DSM у них нет приложения для хранения паролей)) Ничем не лучше lastpass или Bitwarden. Компания тратит трудовые ресурсы на разработку ненужных приложений и не может довести до ума новые приложения photo, office, active backup, hyper backup. К каждому из этих приложений масса вопросов. Компания только только может успевать догонять решения MS и Google, Acronis. Но продолжает делать целую кучу полуфабрикатов. Жаль.

为什么C2 Password是网络版本?而不是以套件的形式出现在我的NAS里面?

After years waiting for DSM 7 now we have to wait years to get a password add for DSM ! How could it be possible to release it on your cloud instead of our NAS??? If there is something we need to keep safe home are PASSWORDS ! Sorry but can't give more than 2 stars ! RELEASE DSM VERSION ! That's all EVERY SYNOLOGY USERS need and wants as we have enough password manager on the web ! I Hope someone will read this and report it to the technical manager !

This is the worst password manager ever seen, the encryption key loading so it says it's not correct, after recovery I change it but it only works ONCE. The worst manager and extension that has appeared, I advise everyone to bypass it in a wide arc. If I could give ZERO, I would give it because it took my time and effort and I didn't get anything in return.

Funktioniert nicht. In der Erweiterung steht immer "kein encrytion Key eingerichtet". Will mann das dann tun, dann lädt die C2 Website in einer Endlosschleife.
