For security reasons, we always recommend to set strong and long passwords.
But we also advise to not set the password too long
Why?
The Linux console has a timeout and in case of a for example 60-character long password you may always miss the time and can't login via the rescue console in case SSH crashes.
We advise setting the password secure (for example 20 is more than long enough) and setting ssh to key auth. This way a brute-force is impossible (as password logins won't work) and you still can reach the server via the rescue console.
