Hi,

Would it be okay to use a 2FA app, e.g. Authy, Google Authenticator or Microsoft Authenticator, across different devices or is limited to a single device, e.g. phone?

Any advice would be appreciated, please.

Thank you.

Yes, I know, but I also like to have some advice or suggestions from people too, e.g. where different people can engage with the topic.
