One of my friends is leaving to Finland tonight, and I encouraged him to enable 2 step verification (2FA – 2 factor authentication) for all his online accounts as soon as possible.
He’s moving to a new country, is going to login from new IP addresses and there’s a fair chance that the service would block his attempts to login, primarily for his account’s security.
There’s going to be SMS sent to his mobile number, only to see that he cannot use it, because he does not have access to the mobile number in a foreign country.
That’s when tools like Authy, Duo and Google Authenticator come handy. One can setup 2 step verification for any TOTP-based 2 step verification process and carry the codes securely using Authy apps for Android, iOS or Google Chrome.
Learn what 2 step verification is, and how to setup Authy for common accounts on this post I wrote.
