I absolutely wouldn't recommend Authy. It is closed source. Your 2FA codes are stored in their servers. They collect a lot of information about you, including device information, email address, phone number, IP address, location, log in history, and more. If you lose access to your account, they require full KYC with copies of your ID to recover your account. This is an unnecessary security and privacy risk, for something you can do safely yourself as described above.
o_e_l_e_o, AFAIK authy do not do that.
Authy doesn't request location access neither email address. The only thing authy gets it the phone number.
I never even heard about they requestiing KYC documents.
I look at their help page (
https://support.authy.com/hc/en-us#) and the word KYC or Documents is not even mentioned anywhere.... where did you see that they require KYC?
