Yes, I understand, but it’s a stupid limit.
Every time you are forced to do a manual login through remote connection, and you cannot do copy and paste with password field (like Windows login), you are obliged to use short or mnemonic password, this reduce a lot security.
The only way to be sure about remote security is to use long randomly generated password, but this is impossible in remote software like NoMachine (or about any other, except for Windows RDP).
