Truth! SMS is not a secure #2fa channel for Instagram or any service; and I've just switched what I could to @Authy. Read up on these #simhijacking #portoutscam hacks (and how to mitigate risk) with this great series by @lorenzofb for @Motherboard: motherboard.vice.com/en_us/topic/si…

For its part, @Instagram is rolling out support for third-party #2FA authentication code apps now (like @Authy or Google Authenticator) now, as an alternative to SMS. I've been checking my Settings > Two-Factor screen relentlessly! help.instagram.com/15824741551979…
Because, as @lorenzofb reports, carrier insiders are helping scammers take over phone SIMs even when you add account PINs, I wonder whether using SMS for #2FA is better than no 2FA at all. #simhijacking is relatively rare, so for most folks I think it is. motherboard.vice.com/en_us/article/…
A good way to avoid SIM-based attacks is to use VoIP services that don't use SIMs, like Google Voice, as the backup or #2FA number for online services. But make sure that VoIP account is secure as well. wired.com/story/sim-swap… #simhijacking #portoutscam
