Why tf Google is outsourcing security?
Google is not a mobile phone network provider. SMS routing is not really their cup of tea. It is an industry with lots of established players, lota of local issues, and little to gain for Google. If it where up to Google, everyone would be using their app instead of SMS.
Aegis Authenticator, in case someone was wondering what to use
I'm not that tech savy, so I was under the impression sms 2FA was the best way to go - why is app based authentication better?
On top of all the other good answers, someone can also just SIM hijack your phone number by social engineering your phone provider into activating a new SIM card.
And it's usually much easier than one would think/hope.

SMS-based can be intercepted, while app-based are calculated on your phone. If you're using SMS -based, all someone needs to do is take over your phone, and they're getting your 2FA codes. Here's how easy that is: https://m.youtube.com/watch?v=lc7scxvKQOo

Piped is a privacy-respecting open-source alternative frontend to YouTube.
I'm open-source; check me out at GitHub.
Someone already explained it, but here's a ranking of the different methods which are commonly used in terms of security, from bad to good:
- No 2FA
- SMS/Phone-based TOTP (TOTP = the normally 6 digit code)
- App-based TOTP
- Hardware-based TOTP
- Hardware-token (Fido2/WebAuthn/Passkeys)
Thanks, what level would you recommend for an more or less average user? Would guess my most sensitive data are bank and google account.
Go app based, and keep it something that doesn't sync (preferably) to external servers.
I'm using andOTP currently for mine. You can create backups every now and again and store them off your phone for safe keeping too 🙂
Thank you, will look more into it.
Cause SMS is not encrypted, so your phone provider and any routing company like this one can read your texts, phone numbers can be spoofed (not sure about this one), or stolen via social engineering (someone calls your phone provider claiming it's you and u lost your phone or something, then gets access to your number).
There's probably a lot more issues with it, i don't remember them atm, but should be pretty easy to find with a search if you're still curious.
Also, physical phone stolen, and the thief just pops the simcard out and puts it in another phone.

I still use Authy, I know it's frowned upon in the privacy community but it's worked well enough for me so far. With them shutting down their desktop app though I see no reason not to switch to Aegis at some point in the near future. Just a pain in the backside setting it all up again as Authy doesn't let you export your 2FA.

Awesome.
It's a great recommendation to use app-based 2FA, except that lots of services seem to insist on and only offer SMS OTP.
For instance out of all the financial establishments I do business with, only one offers the option. The big name players don't, it's only some tiny little mom & pop CU that does.
It's very much a business adoption issue.
Not sure if you do business with them, but Charles Schwab does have a app-based MFA option - although that’s limited to Symantec’s own TOTP MFA.

App-based is also unacceptable if it’s a proprietary implementation
TOTP/HOTP are the best standards right now
I like a combo of Yubikey and Bitwarden, personally.
Yeah, Yubikey fits - it implements TOTP/HOTP, and bitwarden is great
Just “app-based” worried me about apps rolling their own implementations instead of using standards

This is the best summary I could come up with:
The Asian technology and internet company YX International manufactures cellular networking equipment and provides SMS text message routing services.
Anurag Sen, a good-faith security researcher and expert in discovering sensitive but inadvertently exposed datasets leaking to the internet, found the database.
Two-factor authentication (2FA) offers greater protection against online account hijacks that rely on password theft by sending an additional code to a trusted device, such as someone’s phone.
Two-factor codes and password resets, like the ones found in the exposed database, typically expire after a few minutes or once they are used.
But codes sent over SMS text messages are not as secure as stronger forms of 2FA — an app-based code generator, for example — since SMS text messages are prone to interception or exposure, or in this case, leaking from a database onto the open web.
When asked by TechCrunch, the YX International representative said that the server did not store access logs, which would have determined if anyone other than Sen discovered the exposed database and its contents.
