CipherDrive™ may ask you to unlock your vault again even when you are still signed in to Ackaia ID.
This is expected because account authentication and file decryption are separate security layers.
You may be asked to unlock the vault again after:
clearing browser or site data;
using a new browser profile;
changing devices;
removing remembered local access;
signing out;
a security-related reset;
local application data being removed;
changes to browser or storage permissions;
a client or protocol update that requires fresh key access.
Ackaia ID proves your account identity and authorization.
CipherDrive's vault still needs the cryptographic material required to unwrap the master key and per-file keys.
If the product treated a normal account login as sufficient to recreate all lost file keys from the server, that would weaken the zero-knowledge separation between identity and encrypted content.
Not necessarily.
A vault-unlock prompt is often caused by normal local-state changes rather than an attack.
However, if the prompt appears together with unfamiliar sessions, unexpected account changes, or other suspicious activity, review your Ackaia ID security state from a trusted device.
If CipherDrive offers a remembered-access feature, use it only on a device you trust and control.
Remembered access improves convenience but increases the value of the local endpoint because key material or unlock state may remain available there.
Check whether another trusted device still has valid access and whether the current client offers a supported recovery method.
If every valid cryptographic path is gone, Ackaia may be technically unable to decrypt your files.
A vault unlock prompt protects the cryptographic layer. It is not simply a duplicate login screen.
