forwarding port 22 safe? (alien.top)

i want to remotely ssh to my home server, and I was wondering if I could just forward port 22 with disabling password login and use pubkey authentication will be safe enough?

Port forwarding will work, but it has major downsides

  1. Will draw attention of bots
  2. Secure as long as there are no security holes in openssh (which is rare but has happened)
  3. You _must_ harden the ssh server by disabling password auth, putting behind fail2ban

There are far better and safer alternatives that I would recommend over exposing a raw port to the world.

  1. Tailscale
  2. Wireguard/OpenVPN

I would also add twingate as an alternative.
