OKX Registration: Phone Number or Email? A Comparative Guide
When registering anOKXaccount, you actually have no choice — the official requirement is to bind both a phone number and an email address simultaneously. There is no option to pick one over the other. So the real answer to this question is: use whichever you have ready first to register, and you will need to add the other as well. What truly requires your decision is: which one will you use as the primary security verification channel in daily use? For users accustomed to authenticator apps (e.g., Google Authenticator), their security level is higher than SMS verification.

Current Official Policy: No Choice Between the Two
According to the latest instructions from the OKX official help center, whether registering via web or app, you must fill in both an email and a phone number and verify them to complete registration. The platform does not offer an option to use "phone only" or "email only" during the registration process; both are mandatory fields.
So What Does "Which One to Use for Registration" Mean?
Since both are bound, the discussion actually focuses on the priority of security verification and user experience differences. Although you have both channels linked, during certain sensitive operations (e.g., withdrawing funds, changing security settings) that require identity verification, the platform may let you choose one method to receive a verification code.
| Comparison Item | Phone Number | |
|---|---|---|
| Registration Role | Mandatory | Mandatory |
| Main Risks | SIM swap attacks, fake base station interception, carrier interface leaks | Password leaks, email account theft, phishing emails |
| Security Advice | Use as a secondary verification channel; be cautious of SMS code interception | Bind a dedicated email, enable independent 2FA for email, set up anti-phishing code |
| Practical Tips | Set a dedicated fund password for your phone number on the platform, with separate verification for withdrawals | Use as the core channel for receiving system notifications and identity verification |
Key Reminder: Authenticator Apps Offer Higher Security
In June 2024, OKX experienced user asset incidents related to security settings, sparking widespread community discussion about verification methods. The focus was: when a user has already bound Google Authenticator (GA), should some operations allow switching to the lower-security SMS verification?
Conclusion: GA is widely considered to have higher security than SMS verification. OKX officials also recommend users enable an authenticator app as their 2FA method.
Action Advice: After registration, go to [Security Center] and be sure to bind Google Authenticator. Make GA your most important security baseline, rather than relying on SMS codes.
Registration Checklist
When registering an OKX account, follow this order:
Prepare a commonly used email (QQ, 163, Outlook, etc.).
Prepare a personal phone number that can receive international SMS.
During registration, fill in both email and phone number, and complete dual verification.
Immediately after registration, go to [Security Center], bind Google Authenticator (GA), and save the backup key.

FAQ
Q: If I only have a phone number and no email, can I register first and add the email later?A: The current official registration process requires both email and phone number to be verified simultaneously to complete registration, so you cannot skip the email step. We recommend registering a free email (e.g., QQ Mail) first before completing registration.
Q: If I use QQ Mail to register, will I fail to receive verification codes?A: OKX officially lists QQ Mail as one of the acceptable registration emails. If you don't receive the email, check your spam folder or confirm your mailbox is not full; if the issue persists, try another email (e.g., Outlook).
Q: If my bound phone number is no longer in use, what impact will that have?A: The impact is significant. Changing your phone number requires verification using the old phone number or email + GA. We recommend proactively updating the binding before deactivating your old phone number. After changing, withdrawals will be blocked for 24 hours.
