The unique security concept of Solo Secure protects against read-out of the sensitive key material stored on the device.
Due to this security concept, it is not possible to run your own / modified firmware on the device.
However, it is open source hardware and firmware, so there is also a Solo Hacker with unprotected bootloader for makers and developers.
Secure your accounts with two-factor authentication and stay protected against phishing and other online attacks. Works with Google, Facebook, Twitter, Dropbox, Github and all sign-in services with FIDO2 or FIDO U2F support.
Works with Google, Facebook, Twitter, Dropbox, Github, and anything that supports FIDO2 or FIDO U2F
Solo Hacker comes with the latest unsigned firmware. You can lock it down yourself to prevent keys being stolen by someone with physical access to the token, but it’s highly recommended to use Solo Secure for everyday use.
