Hello,
We’ve started working on the design for the OTP features, we’re currently working on the wireframes and will soon move to the user stories / technical specs.
You have have a look here:
We still need to work on the quick access integration. We don’t generally give deadlines, because as explained elsewhere, we’re a small team and therefore we have comparatively to other projects a quite design-heavy approach in order to reduce security risks. So bear with us, we’re not twiddling our thumbs
