Did you ever reset your mobile phone?
and got a trading and market restriction after reinstaling the steam application?
just because you didn't tap the right button?

Steam doesnt realy tell you about the trading and market restriction until you remove the Authentication or until it is to late!
this guide shows you the right way in order to keep Steams Mobile Authentication.

IMPORTANT

• This guide will just work if you still have access to your previous mobile phone number.
  
  
• I have heard in some cases you will not be able to sell on the community market for 2 days.
  
  
• I do not take responsibility for any trading and market restriction just because you tapped on the wrong button!

log into your steam account on your mobile phone with password and username.

since you do not have access to your Mobile Authentication anymore, tap on:

please help
I no longer have access to
my Mobile Authenticator
codes

DO NOT tap REMOVE AUTHENTICATOR.
this will give you a trading and market restriction for two weeks!

instead tap on:

Use this device
and get authenticator coder
on this app

choose
"OK! Send me the text message"
in order to get a verification code via email.

steam should send you a text message with a code attached. copy this code.

enter the code you recieved in the text message
and tap on:

Submit
I entered the code above

thank you for stopping by.
