a thief was able to try to break into my bank account and tried to transfer money out. My bank caught it but they said it happened by having a 2FA text message sent to a phone number on my account. But the phone number they said was compromised was one that is a landline, its an old phone number my family has that my parents put on the account when they opened it for me as a kid.
How can a landline get a text message? and even if it was possible to get a text to a landline phone, how would the thief access the code?

If the service allows it, you should move away from SMS based 2FA and instead use an authenticator app. It’s been [deprecated by NIST](https://www.nist.gov/blogs/cybersecurity-insights/questionsand-buzz-surrounding-draft-nist-special-publication-800-63-3) since 2016 for exactly these kinds of reasons – it’s not particularly hard for the message to be intercepted.
