How do I update a Microsoft or Gmail recovery number after switching to a cell phone?
Answer
When your recovery phone number is outdated after dropping a landline, update security info while still signed in if possible, or use Forgot password with alternate email and other verified methods to regain access, then add the new cell number.
Before you start: stop right away if…
- Never share passwords or one-time codes with anyone who contacts you unexpectedly about account recovery.
Follow these steps
Update the number while signed in if possible
If you can still open the mailbox, go to the official Google or Microsoft security/security-info page, remove or replace the old landline, and add the new cell number.
You should see: The new cell number appears as a verified recovery option.
Use Forgot password with remaining methods
If you cannot sign in, open the official sign-in page, choose Forgot password, and follow prompts using an alternate email, authenticator app, or other verified method instead of the dead landline.
You should see: You receive a code through a method you still control, or the recovery flow explains the next wait or review step.
Create a new password after verification
After you pass verification, set a new password on the official page and save it in a password manager or secure place you control.
You should see: You can sign in with the new password.
Confirm the new cell number is primary for recovery
Sign back into security settings and make sure the cell number is listed and preferred for verification, then remove the obsolete landline if it still appears.
You should see: Future codes go to the cell phone, not the old landline.

Extra tips
What to look for: Sign-in or recovery screens that still show or request the old landline number
Before you change anything: List every alternate email and authenticator app still linked to the account. Use only the official Google or Microsoft account websites. Do not give codes to unexpected callers. Keep the new cell phone nearby for SMS verification.
