Genuine question - Which keyfobs support scanning QR code presented by an online service to add the TOTP seed and then generate TOTP codes?
Any cross-platform recommendations for TOTP program that works on Windows, Linux, Mac?
- striking 4y agoYou type the seed in. Services almost unilaterally give you the option to get a seed code instead. Even if they don't, you can scan the QR code and get the seed out of it.
- rgoulter 4y agoQR code scanning is intended for mobile phone cameras as a way of communicating a TOTP secret. When presented with a TOTP secret, every website I've seen has presented the option to show the TOTP secret as text, which can be copied across. A password database like KeepassXC can store the TOTPs. FIDO / U2F hardware like Yubikeys (or various alternatives) are also a convenient second factor.
