If you can log into the web app on an existing device, your best bet is to either:
- Turn on 2FA, so you can use it everywhere without the email delay problem.

- Contact customer support.
I assume this means a wholly new account?
You can change the account email via the web app. It’s highly recommended that you export the vault for backup first, as vault corruption is possible with this procedure.
