Figure — Example SMS verification
Steps
{{bg: neutral-50, round-12, px-14, py-10, display: block::
- Open Settings → Security → Two-factor authentication
- Choose Set up SMS
- Select your country code and enter your phone number
- Send code
- Enter the 6-digit code you receive → Verify
- Save backup codes securely (password manager)
- Done — You’ll be prompted for a code at sign-in }}
Tip — Some carriers throttle delivery. If a code is slow, request a fresh one instead of retrying the old SMS.
Security notes
- SMS is convenient but less secure (SIM-swap & phishing risks)
- Use SMS as fallback — prefer an authenticator app or hardware key as primary
Common errors & fixes
| Error | Example | Fix |
|---|---|---|
| Code expired | Message arrived late | Request a new code; enter within 30–60 seconds |
| Invalid code | Typo / using a prior code | Wait for the next SMS; retype carefully |
| Too many attempts | Rate limit triggered | Wait a few minutes, then try again |
| Number not accepted | Wrong format | Include country code; drop leading zero after the prefix |
| No messages received | Carrier filtering / blocked sender | Toggle airplane mode, check signal; allow short-code SMS |
Tip — If you change phone numbers, update it here first to avoid lockouts.
Best practices
- Add an authenticator app too, for stronger protection
- Keep your number up to date in Settings → Profile
- Never share codes with anyone — not even support
