A new addition to the Proton family, available from https://proton.me/authenticator, this is the only tool you’ll need for your 2FA requirements. I particularly love the fact it’s available as a Windows app also.
Set up the Proton Authentication on your phone – if you’re using another authentication tool (I was using Aegis) you can export codes as a JSON file then import them to Proton Authenticator.
Finally….. if you’re using a desktop and a phone version of Authenticator, you can sync your 2FA codes across devices. It’s not turned on by default. Simply go into Settings for each device you’ve got Authenticator installed, go into Settings and select the “Sync Between Devices” option. You’ll need a Proton account for that (you can get a free account with no obligation – I use Proton anyway so wasn’t any great shakes)
Bing Bang Bosh! Done in 2 mins!
I’m currently having a really good Proton experience having switched from my Google tools. Now using Firefox as my main browser.
