Linux Password Sorry Try Again Fedora

Sometimes yous need to enter a countersign into the final, usually for sudo or su commands, which lets users execute a command with super user privileges. This is fairly typical for allowing access to read or modify something that would otherwise not be possible with a standard user account. Y'all'll commonly see sudo prefixing some other command, looking something like "sudo nano /etc/hosts". Though about of the command line and sudo is mostly only appropriate for advanced users, occasionally more coincidental calculator users may need to turn to the Terminal, possibly to enable a characteristic, modify a organization file, or even for troubleshooting purposes. For novice users who wind upward at the command line, a very common question occurs with entering passwords into the Concluding, almost ever related to sudo and the apparent inability to type a password into the command line of Mac OS X (or Linux for that matter).

But here's the thing; Terminal does let you blazon your password, it simply doesn't look like it. The cursor on screen will not motion, and there is no indicator the password is beingness entered at all. This is intentional and serves every bit a security machinery, unlike entering a password into a web form or a standard GUI login screen, which is typically masked as asterisks like ******** or bullets like •••••••••••••, the lack of anything showing is entirely intentional and there is no such indication of entering passwords at the command line. The reason is rather simple, information technology provides no indication for how long a password is, offer some further obfuscation to password entry.

If this sounds confusing, it's non at all, here's how it works in practice. Let's say yous execute a control that requires sudo access, thus bringing up the familiar "Password:" entry.

% sudo cat /etc/underground.conf
Countersign:

When the Password: asking comes up, type the countersign anyway, even though nothing is showing upwards then hit Return when finished. Again, there is no indication that a password is being entered, and that is intentional.

Then allow's run through the prior example command once again, pretending the admin password on this detail machine is "Monkey123", you lot'd type that password as information technology's requested, despite not showing up at all, pregnant the sequence would exist something like:

% sudo true cat /etc/cloak-and-dagger.conf
Password: Monkey123 (hitting Return cardinal)

This volition execute the command. And no, Monkey123 (or any the admin password is) will non appear on screen, neither will any asterisks or bullets.

To be 100% absolutely clear:

Terminal passwords do not show upward when typed as a security mensurate, type the password when requested anyway and hit return

Typing the countersign and hitting return volition submit the countersign for authentication, and assuming the password was entered correctly, the control will execute as expected.

Typically a user but has to experience this once or twice to empathise that's how it works, but it remains a great question for users who are just starting to go exposure to the command line. And one time you lot know, you tin pass the knowledge along to others, so if someone asks you "why doesn't the Final let me type a password?", yous tin can at present respond and explain information technology to them.

For those wondering, yes this default behavior tin be changed to testify asterisks for each character entered as the countersign in the command line, for sudo, su, or whatever else you're doing. Still, making that change is not recommended, and we're not going to cover information technology in this particular commodity… perhaps in the future if there is some interest in doing then.

What do y'all think of this security mensurate that hides the countersign length and entry in Terminal? It has been standard practice for a long time for the unix world, but do you find information technology useful on the Mac as well? Let us know your thoughts in the comments below.
