Not strictly — SMS is helpful, but it’s not the best or only option for fraud alerts and account security.
Best practice
- Enable alerts through your bank/app/email
- Use app-based or push notifications for transactions and login alerts
- For sign-in security, prefer authenticator apps or passkeys over SMS when available
Why SMS isn’t ideal
- It can be intercepted via SIM swapping
- Text messages can be delayed or fail when you have no signal
- It’s less secure than app-based authentication
When SMS is still useful
- As a backup if you can’t use an authenticator app
- For fraud alert notifications if that’s the only option your bank offers
Recommendation
If your bank supports it, use:
- Push/app alerts
- Authenticator app or passkey
- SMS only as backup
If you want, I can help you set up a more secure alert and login setup for your bank or email accounts.
