Signed-in phones
Signed-in phones lists every phone that can open your account. Remove one you no longer trust and it must sign in again.
Where
Settings > Advanced actions > Signed-in phones.
What you see
- This phone and any Another phone entries.
- When each was last used (or "Not used yet").
- A Remove button. Removing a phone makes it lose access immediately. You can sign in again from that phone if you still have your key.
If only one phone is signed in, the screen says "Only this phone is signed in."
When to use it
- After moving to a new phone.
- After signing in on a new phone.
- If a phone was lost or sold.
Removing a phone does not remove the key on it. If a phone could be in someone else's hands, also replace your keys.
