[Feature Request] Passphrase-QR scan text formatted QR generated by separate SW #499

If you use passphrases as part of your security model it would be nice to be able to scan text QR codes to quickly import a longer string of text.

Thank you for the suggestion. It's something that's been asked about multiple times and these are my thoughts on it: writing a passphrase down, or transcribing it to a QR code, transforms the passphrase from something you know, into something that you have. A seed phrase + passphrase has the same functional authentication threshhold as a 2-of-2 multisig wallet. If you're looking for a wallet that's protected by two things that you "have" I would consider just using a 2-of-2.
