✅ 1️⃣ Check Your GitHub 2FA Method
First question:

Are you setting up:

✅ TOTP (Authenticator App)
or
✅ Passkey / Windows Hello?
These are different.

If you're using Microsoft Authenticator, you must choose:

“Set up using an app”
NOT passkey.

✅ 2️⃣ Time Sync Issue (Very Common)
If you scan the QR code but GitHub says:

“Invalid code”

Then most likely your system time is slightly out of sync.

On Windows 11:

Go to Settings → Time & Language → Date & Time
Turn on:
✅ Set time automatically
✅ Set time zone automatically
Click Sync now
Then try again.

TOTP codes are time-based — even 30 seconds difference breaks it.

✅ 3️⃣ Are You Using Microsoft Authenticator on Desktop?
Important:

Microsoft Authenticator officially works best on mobile devices (Android/iOS).

If you're trying to use:

Windows desktop app
or
Browser extension
It may not support standard TOTP properly.

👉 Recommended:
Use Microsoft Authenticator on your phone.
