What Allowlisting and 2FA Each Protect
Security settings are meant to slow attackers down. Use withdrawal whitelists, 2FA, email protection, and test transfers together.
Checks Before Changing Security Settings
- Crypto.com notes that address whitelisting requires 2FA when using an untrusted device.
- Kraken requires confirmation for new withdrawal addresses and notes security-related withdrawal holds in some cases.
- Security features vary by exchange, but the core is protecting login, withdrawal addresses, and email.
Recommended Setup Order
- Enable authenticator-based 2FA instead of relying only on SMS.
- Use withdrawal whitelists for your own wallet or trusted exchange addresses.
- Protect your email with 2FA and review recovery options.
- After adding an address, send a small test transfer first.
- Review login devices, API keys, withdrawal history, and security alerts regularly.
Common Mistakes
- Securing the exchange account but leaving email unprotected.
- Saving backup codes as cloud photo screenshots.
- Turning off whitelists for convenience.

FAQ
Q: Is SMS 2FA enough?
A: It is better than nothing, but authenticator apps or hardware keys are safer against SIM and social engineering risks.

A: Yes, but that friction is the point. It helps prevent instant theft.
Q: Should I review API keys?
A: Yes. Disable unused keys and never allow withdrawal permission unless absolutely necessary.
