Hello, a blog article "Reliable, Secure and Universal Backup for U2F Token" dmitryfrank.com/articles/backup_u2f_token proposes a very elegant way to create a backup of an U2F token using 2 tokens of the same type. Is this possible with this device? I had to remove http: at the link above because external links aren't allowed here, so just copy and paste the remaining URL into your browser to lok at the blog article. Thanks, Martin
