IMHO no password is best method until a password is set (like it was with telnet and now with new paswordless SSH). A default password is just false sense of security, there is none! Otherwise "encouraging" to set one and how can be discussed... Olmari On Thu, Sep 10, 2015 at 3:14 AM, Ben Fransk

I'm copying this to the list because it was sent directly to me... There are definitely many ways of "encouraging" people to change the password which could be explored, another example is the WAN interface could be disabled until the password is set. A few more thoughts on something like that

A couple of thoughts on some of the discussion around this: 1) I would be a proponent of a pre-set password, SSH without a password is very unusual behavior. I understand that there have been some comments "Any preset password is asking for users to leave it default." I fail to see how this is

Hello Michael, that is interesting, though I guess since these are mainly our default it shouldn't be too hard for someone manufacturing to change the config and readd a simple init-script for telnetd if that is really required. Lack of entropy doesn't seem to be too much of an issue here, in fac

Nak on setting a default password. The blank password has served its purpose well for years now. Any preset password is asking for users to leave it default. The only problem with blank ssh logins is it removes one of the ways openwrt encouraged the user to set a password. A banner that warns abou
