Choosing the right sign-up method dictates how much metadata third parties receive, how securely your profile sits against credential-stuffing attacks, and how easily you can reclaim ownership during an account lockout.
| Registration Channel | Primary Verification | Data Exposure Risk | Account Recovery Speed |
|---|---|---|---|
| Dedicated Email Address | 6-digit inbox code | Low (No carrier or hardware linking) | Moderate (1, 3 minutes via inbox) |
| Direct Phone Number | SMS OTP verification | High (SIM-swap risk, cross-ad syncing) | Instantaneous (Under 30 seconds) |
| Third-Party SSO (Apple/Google) | OAuth 2.0 Token | Moderate (Ties identity to platform ecosystem) | Immediate, but relies on host provider |
| Desktop Web Browser | Email code + Puzzle challenge | Very Low (Zero mobile sensor data shared) | Moderate (Standard web recovery) |
