Enter Steam Guard Authenticator recovery code (starts with R). Retrieve?
I was logged out of steam to log in I need steam guard authentication but I had deleted the app on my phone now I need the recovery code that starts with r I can't find it anymore is there a way to get it back
No.
Since you don’t have access to the Authenticator and you haven’t written your Recoveringsocde as Steam wanted it from you, you’ll have to contact the support now to get access to the account again.
