«This account has no phone that can approve.» (no_device)

Symptom

When asking for a phone approval, the console shows «This account has no phone that can approve.» (API 409 no_device). A phone that tries to approve may receive 403 device_not_active.

Cause

• You never linked a phone to this account.
• Linking stopped halfway: the phone shows «Waiting for confirmation in the browser» and cannot approve yet.
• Every phone was removed, by you or by your administrator.

Fix

1. Sign in with your passkey, or another method your organization allows.
2. Open «My phones» and check the list.
3. If the phone is not there, link it again; see Link your phone.
4. If linking stopped halfway, remove the account on the phone and start again in the browser.

If you cannot sign in at all, use your recovery codes or ask your helpdesk for help.

When to escalate

If the phone shows as active in the console and still gets this error, contact support with the time and the phone's name.
