stram guard

[DönerTaz Virtus.noPRO]

I restarted my phone to factory settings, I downloaded the Steam application with the main account, nothing happened, but when I wanted to log in to my second account, I couldn't because it required Steam Guard, which I don't have in the application and I would like to get it back, I wrote to Steam, I described the situation, but if I want provide some evidence, I get an error: Access is denied (15) does anyone know what I can do?

Did you save the Recovery code, like it told you to when you first set up the mobile app?

1. Check Email for Steam Guard Code
When you try to log in to your second account, Steam should send a Steam Guard code to the email address associated with the account.
Check your email inbox (and spam/junk folders) for the Steam Guard code.
2. Re-enable Steam Guard on Your Account
If you can't find the Steam Guard option in your app, it may have been disabled during the factory reset. Try these steps:
Go to Steam Settings > Account > Manage Steam Guard.
Make sure Steam Guard is enabled.
Choose whether you want to receive Steam Guard codes via email or the mobile app.
3. Try Steam Mobile App Verification
If Steam Guard isn't working through the app, try uninstalling and reinstalling the Steam app to reset it.
Make sure your mobile number is linked to your Steam account and verify via the app if necessary.
4. Clear Steam App Cache
If you get the "Access is denied (15)" error when contacting Steam support, try clearing the cache for the Steam app and attempt logging in again.
5. Contact Steam Support Again
If you still can't resolve the issue, try contacting Steam Support again and explain your situation in more detail. They may ask you for additional information or steps to help recover your account.
