@protonmail Awesome, and great protocol to also publish the report by @cure53 , I know they're awesome people! :)
This makes you a serious contender to 1Password IMHO who also publish their reports but don't publish the source code. There's also Bitwarden which is also audited and open source of course.
This leads me to the questions:
1. Do you plan on open sourcing the server and supporting self-hosting?
2. What's the support of passkeys?
3. Is in-depth integration into the OS planned, e.g., through Linux SecretService API and/or wayland protocols (input-methods und text-input AFAIK)
