- The first factor is given by the SSH public key. Please upload your SSH _public_ key to our dedicated [Ramses key upload website](https://ramses-umc.itcc.uni-koeln.de/web-sshkey/login). You can find general information on public key authentication [here](https://www.ssh.com/academy/ssh/public-key-authentication).
- The second factor involves the [Cisco Duo app](https://duo.com/product/multi-factor-authentication-mfa/duo-mobile-app). To use it, you will need to enroll your account, see [cisco-duo-setup.pdf](uploads/cd518a29f4362a9383c7345a975ed065/cisco-duo-setup.pdf) .
If you own a [Yubikey](https://en.wikipedia.org/wiki/YubiKey) hardware token, you can also use it (in [OTP](https://en.wikipedia.org/wiki/One-time_password) mode) as the second authentication factor instead of Cisco Duo. If you are interested in this solution, please contact the [HPC-Team](mailto:hpc-mgr@uni-koeln.de). Please note: we can't provide Yubikeys to users, but its purchase could be a worthwhile investment for about 50€.
