The advantage over tpm2-otp is asymmetric cryptography, so you don't need to store and protect the secret on both devices, but have one secret on each device and the public key on multiple devices.
On the first pairing, you need to trust both devices. You create a QR-Code via the share button on device 1, scan it via the "add-friend"-button on device 2. So if you trust device 2 in the future, you can share-and-scan again to verify, that device 1 is really the device you initially trusted in the past.
You can use the same for people you meet over the internet, when you have a secure channel already. One can make a screenshot of the qr-code, sign it and send it to the other party. When you meet in real-life, the other party can proof, that it is really the other party.
