  4. # To enabled agent forwarding support add the following to
  5. # your .zshrc file:
  6. #
  7. # zstyle :omz:plugins:ssh-agent agent-forwarding on
  8. #
  9. # To load multiple identities use the identities style, For
  10. # example:
  11. #
  12. # zstyle :omz:plugins:ssh-agent identities id_rsa id_rsa2 id_github
  13. #
  14. # To set the maximum lifetime of the identities, use the
  15. # lifetime style. The lifetime may be specified in seconds
  16. # or as described in sshd_config(5) (see TIME FORMATS)
  17. # If left unspecified, the default lifetime is forever.
  18. #
  19. # zstyle :omz:plugins:ssh-agent lifetime 4h
