How to Stop Using SMS Codes for Your Most Important Accounts

To stop using SMS codes for your most important accounts, add stronger authentication where available: passkeys, security keys, or authenticator apps. Start with primary email, banking, payment apps, password manager, cloud storage, phone carrier, and work accounts.

Do not remove SMS until you understand recovery options and have backup codes or another trusted method. The goal is stronger security without locking yourself out.

SMS is often better than no MFA, but it depends on phone-number control. SIM swapping, port-out fraud, lost phones, and phishing can weaken it.

Text messages can be affected by SIM swap, number porting, phone theft, shared devices, malware, and scams that trick people into reading codes aloud. The FCC warns about SIM swapping and port-out fraud because attackers may seek control of a number.

CISA recommends MFA, and stronger methods can reduce reliance on phone numbers. NIST guidance recognizes phishing-resistant authenticators such as passkeys.

For consumers, the practical message is simple: keep MFA, but upgrade the method where you can.

Review security settings for important accounts. Write down which ones use SMS, which offer passkeys, which support authenticator apps, and which provide backup codes.

Do not share codes during this process. If you receive a code you did not request, review the account directly.

Your email controls password resets for many accounts. Add a stronger MFA method there first, then save backup codes securely.

Review recovery email, recovery phone, sessions, and connected apps while you are inside settings.

Passkeys can reduce password and phishing risk because you do not type a password into a page. Follow official provider guidance for each account.

Keep recovery methods current before removing older methods.

Authenticator apps and security keys can reduce dependence on text messages. Add them from the official account security page.

Store backup codes somewhere secure and accessible during phone loss.

Even if you reduce SMS codes, your phone number still matters for calls, alerts, and some recovery flows. Set a carrier PIN and ask about port protection.

Monitor sudden service loss or carrier account changes.

If your phone number appears in exposure data, expect more scam texts. Never enter one-time codes into exposure tools or share them with callers.

A clean result does not guarantee the number is not on spam or phishing lists.
