online courses: 2FA backup codes and lost-phone recovery (2026-08-28)

Compare Courses tests 2FA recovery without the old phone for “learn ai programming” in online courses on 2026-08-28 across Udemy, Alura, and Coursera. Focus: online courses. Annual is blocked until backup codes open the account.

How Udemy, Alura, and Coursera fail recovery

Udemy fails without downloadable codes. Alura fails if online courses needs the old SIM. Coursera is the control: if its backup file opened, do not excuse SMS-only vendors.

Fails that kill compare-courses-recovery-2026-08-28

• Paying Udemy annual with SMS-only 2FA
• Skipping backup codes on Alura
• Leaving online courses on the old phone for Coursera
• Closing before a second-device login
