Hello


Please forgive my ignorance


I’m considering using Signal (desktop messaging app) for (desktop) Gmail’s 2FA.


In other words, instead of Gmail sending an authentication SMS to my smartphone, I would like desktop Gmail to send a SMS, or something else, to Signal (desktop messaging app).


Is it possible??


Again, I apologise for my ignorance

SMS is the worst possible 2FA method. Why you do not consider using proper authenticator app?

Agree with others that 2-step verification via SMS is insecure, and not advisable from a security perspective.

Google Prompts is available for Android and iOS (via signed-in Gmail, Photos, YouTube, Google app) and much easier than actual 2FA apps.

We recommend you use Google prompts as your second step. They’re easier to enter than a verification code and can help protect against SIM swap and other phone number-based hacks.

With 2-Step Verification, also called two-factor authentication, you can add an extra layer of security to your account in case your password is stolen. After you set up 2-Step Verification, you can s

There are numerous articles about Why You Should Not Use SMS for 2FA, as Phone Calls and SMS Texts were never designed to be secure.

Do you use SMS for two-factor authentication? Don't.

Thank you for you kind answers.


I’m sorry, now I realise my question wasn’t clear. My apologies.


My question was more about whether (and how) I could use desktop Signal (messaging app) in relation to Gmail’s 2FA.


Any suggestion, please?

You need to link Signal Desktop to your Phone.

The answer to your question is no, you may get Google 2FA notifications sent to your Signal app/account (depending on how signal works, I haven't used lately) but they won't be encrypted using the Signal protocol and will be in plain text sms. You don't get the added protection in using Signal if one party doesn't use the encryption protocol, basically it's the same as receiving a normal sms.
