Hello there!
I'm getting the following error message when I try to download an app from the Google Play Store:
Security check is needed, try to visit https://accounts.google.com/b/0/DisplayUnlockCaptcha to unlock, or setup an app-specific password
I tried the following:
account password without MFA
account password without MFA and "unsecure" connection enabled (or however that is called)
app-specific password (with MFA)
