You can fix this yourself in a few easy steps via the account management web site.

There are two ways in which you may have messed up your keys:

  1. The keys that were stored in the .ssh subdirectory of your home directory on the cluster were accidentally deleted, or the authorized_keys file was accidentally deleted:
    1. Go to account.vscentrum.be
    2. Choose your institute and log in.
    3. At the top of the page, click 'Edit Account'.
    4. Press the 'Update' button on that web page.
    5. Exercise some patience, within 30 minutes, your account should be accessible again.
  2. You deleted your (private) keys on your own computer, or don't know the passphrase anymore
    1. Generate a new public/private key pair. Follow the procedure outlined in the client sections for Linux, Windows and macOS (formerly OS X).
    2. Go to account.vscentrum.be
    3. Choose your institute and log in.
    4. At the top of the page, click 'Edit Account'.
    5. Upload your new public key adding it in the 'Add Public Key' section of the page. Use 'Browse...' to find your public key, press 'Add' to upload it.
    6. You may now delete the entry for the "lost" key if you know which one that is, but this is not crucial.
    7. Exercise some patience, within 30 minutes, your account should be accessible again.
