How to allow password authentication OR key authentication on CentOS 5.7?

Question

is it possible to enable the use of password authentication or key authentication in CentOS 5.7? All I can find is setting PasswordAuthentication to no which forces the use of keys...

Thanks

Do you mean you want to allow users to login with either password or key, not both? — quanta, Oct 31 '11 at 04:14

Disabling PasswordAuthentication doesn't force keys, it disables password authentication, as advertised.

PubkeyAuthentication determines whether key authentication is allowed.

So, to answer your question directly, the following config allows either password or key auth:

PasswordAuthentication yes
PubkeyAuthentication yes

Do you mean you want something like this:

Match User user1
    PasswordAuthentication no
    RSAAuthentication yes
    PubkeyAuthentication yes

Match User user2
    PasswordAuthentication yes
    RSAAuthentication no
    PubkeyAuthentication no

Where put the content for ? Is it in `ssh_config`? – Timo Jan 11 '19 at 09:07
Place this configuration at the end of `ssh_config` – Davuz Feb 25 '19 at 11:05
Is there a way to do this for root (user1), but the other config for "everyone else"? How does one write "everyone else" in place of user2? – Khom Nazid Jan 05 '21 at 02:27
