hello

I unknow the name for characters as:

∞ ♾ ထ ✄ ✅ ♈ ♉ ♊ ♋ ♌ ☏ ✋ ⏰ ☕

if we use some combination of they in password root, maybe lost access to server?

any keyboard allow write this ?
is more secure my password by use this "very special charcters" ?

I'm not sure how you would get a keyboard to produce those symbols. Maybe password managers would be the way to go.

While the system is probably set up to handle Unicode, I would definitely try it out first on an extra unprivileged account made for the express purpose of testing whether those symbols can be used or not. So make a new, temporary account and give a try. Delete the account when you are done.

If you're talking about remote access, the recommended practice is to disallow remote root log in and use su via an unprivileged account instead. If you have to do remote root log in for backups or some other specialized task then at least use SSH keys or SSH certificates instead and keep the remote password login turned off. See "man sshd_config" for PermitRootLogin and the settings prohibit-password or forced-commands-only.

many thanks :-)

On my Mac, I can just paste these characters into iterm.

use only chars which can be entered directly, without mouse (copy/paste) and any other trick (like pw manager).
I don't think so.

Consider that you might need to enter that root password in an environment such as emergency boot, where features like cutting/pasting and keyboard compose are not available.

Many keyboards have a way to use things like hold crt or alt key or both and then use numbers.

╚ ╚ is alt 456 for example.

Not all login schemes allow doing that but it's use creates a very difficult password to crack.

Have a tab character in your password - that gives you enough trouble.

Putting a euro symbol in your password will block anyone from UK cracking it.

Can you possibly explain in an understandable way what makes you think the euro symbol would block someone from the UK.?
Be logical in what you suggest.

Explaining jokes violates the forum rules.

I've seen people use the Alt keyboard codes way back in the past. It was terrible seeing them retype their password, and it would take them a while.

Just come up with some sufficiently long phrase you like that can be abbreviated to an appropriate length, then do some 733t conversion on it.

I guess using shift-XYZ instead of alt-XYZ will give more secure password (because it is longer). The general 733t conversion is not that safe, but using a personal version could be useful too.

You mean there's an official conversion? :O I was just saying replace some characters with others.
