Use Forgotten password? on the sign-in page at my.quavern.com. Give the address on the account, and a link to choose a new password is sent to it.
What happens
The answer is the same whether or not the address has an account. The page says "if that address has an account, a link is on its way" and nothing more. That is deliberate: it is how an account's existence stays private.
The link lasts thirty minutes and works once.
The mail says what happened, who asked — the country the request came from, not the address — how long the link lasts, and what to do if it was not you.
The second step is not bypassed
If the account has a second step, the reset asks for it too: an authenticator code, a recovery code, a code by SMS under its own rules, or a passkey. A mailbox on its own is never enough, otherwise taking over the mailbox would be taking over the account.
What a successful reset changes
Every session and every refresh token on the account is ended. Sign in again afterwards with the new password.
Your e-mail address is marked verified, because following the link proved you read that mailbox.
Nothing else moves. The address itself is unchanged, and your authenticator app, passkeys and telephone number are untouched.
If nothing arrives
Check the address you typed, and ask again — the request is rate-limited per address and per IP, so wait if you are told to. If the link in the mail does not work, the mail programme may have broken it; ask for a new one and open it within thirty minutes.
If you have lost the second step as well
Use a recovery code. If those are gone too, write to [email protected] with the account address, what factors you had, and the support code shown. There is no route that skips the second step.
