Steam Guard recovery
A new phone, a factory reset, or a broken screen can lock you out of Steam if the mobile authenticator was on the old device. Here is how to get back in and make sure it never happens again.
Step 1
Steam gave you a recovery code starting with “R” when you set up the authenticator. Check your notes, screenshots, or password manager.
Step 2
On the sign-in screen, choose that you no longer have access to the authenticator, then enter the R-code to remove it.
Step 3
At help.steampowered.com, choose that you deleted or lost your authenticator and follow the ownership checks. It can take longer.
Step 4
In the Steam mobile app, set up Steam Guard again. Steam will show a new recovery code.
Step 5
Paste the new R-code into the notes on your Steam card straight away.
The code on your phone is useless if the phone is the thing you lost.
Camera rolls get cleaned up. A vault card does not.
With the code you fix it yourself. Without it you wait on support.
The password and recovery code stay on the same card, where you will look.
Removing or changing the authenticator can trigger a temporary trade and market hold. That is normal and protects you.
Plan phone switches before big trades so the hold does not catch you out.
Create a free vault, then upgrade for a private temp mailbox and burner numbers when the library grows.
