If you need to change your mailbox password, follow these steps.

Open the Vacer Mail interface in your browser
Log in using your email address and password
Navigate to Mailbox Settings
Select Change Password

After changing your password, remember to update it on all connected devices.

Otherwise, your phone or mail client will no longer be able to sync emails.
