5 questionsHow do I change my account email address?
SettingsIn Settings, edit the address then open the confirmation link sent to the new mailbox. The old address stays the account address until the confirmation happens: a typo can never lock you out.
Is my public profile visible to everyone?
ProfileOnly if you turned it on, and it is off by default. Once published it shows your handle, level, badges and certificates — never your email, never your first name, never your exercise answers or conversations. Turning it off takes effect immediately.
Can I use my account on several devices?
AccountYes, with no limit. Progress, Vena Token balance and history are held by the server: you find the same state on every signed-in device.
What happens if I delete my account?
DeletionThe account is disabled straight away: your public profile and certificate pages become unreachable. Data is then permanently erased after thirty days. The deletion is final from the moment you confirm it and cannot be undone: download your certificates and export your data first.
I forgot my password.
Sign-inFrom the sign-in screen, use “Forgot password”. The emailed link is valid for one hour and can only be used once. If you signed up with Google, use that button instead: no password was ever created on our side.
Didn't find it?
