Options
These are the options you can specify that are relevant to Omniauth Trezor:
Challenge-response authentication via TREZOR. To protect against replay attacks, you must use a server-side generated and randomized challenge_hidden for every attempt. You can also provide a visual challenge that will be shown on the device.
-
:visual_challenge
- Text that will be shown on the device (defaults toTime.now.strftime("%Y-%m-%d %H:%M:%S")
) -
:hidden_challenge
- Hidden randomized hex string used to protect agains replay attacks (defaults toSecureRandom.hex(32)
) -
:hosticon
- Optional site icon https url. Should be at least 48x48px.
Callback phase
After successful authentication request.env['omniauth.auth'].extra
contains all data that was used to verify the signature: visual_challenge
, hidden_challenge
, signature
and public_key
for your additional needs (ie. audit log).
