Passwordless Authentication and Passwordless Security

Identity is everything. Protect it with Duo.

It’s no secret — passwords can be a real headache, both for the people who use them and the people who manage them. Over time, we’ve created hundreds of passwords, it’s easy to lose track of them and they’re easily compromised. Fortunately, passwordless authentication is becoming a feasible reality for many businesses. Duo can help you get there.

User Reviews

  • Es un gran proyecto, lo revise a fondo en una de sus primeras versiones, incluso hice una presentracion sobre el. Demostranto que se puede hacer un so libre sin usar linux.
  • Hi, nice implementation and for me a refreshing gimmick. Ultimately, formatting the hard drive in Btrfs was successful and the operating system booted successfully. That's fun. All the best!
  • very good where nowadays there are rarely projects that support old hardware, and the system features are also capable
  • An open source Windows. the project's premise is very good but unfortunately it didn't work on any of the many machines i tested it on. I hope they improve the project soon.
  • Good project.
