Most of the operating systems for Raspberry Pi have default password for accessing the Raspberry Pi.
Raspberry Pi is a credit card sized single board computer which can do everything a normal PC can do. Raspberry Pi Model B+. It is a low cost CPU which can be used as a general purpose PC for web surfing, video streaming eg.
In Raspberry Pi OS, the default username is
pi and the default password is
raspbian. Now, everybody using a Raspberry is knows this is the default password. So when you hookup your raspberry to the internet or network anyone can open up your raspberry pi, well… you will have to open SSH. You don’t want that! You want your Raspberry to be secure! So change that password!!
Changing the password of your Raspberry Pi
To change a password of the current user in Raspberry Pi, execute the
pi@raspberrypi:~ $ passwd Changing password for pi. Current password: New password: Retype new password: passwd: password updated successfully
Do understand that you have to be logged in a the Pi user.
you want to change a password of another user, you can run the
passwd command, as follows:
$ sudo passwd <USERNAME>
So if you are logged in as a different user than Pi and you want to change the password of pi do:
pi@raspberrypi:~ $ sudo passwd root New password: Retype new password: passwd: password updated successfully
That’s all folks!
Why change the Raspberry Pi Password
Theoretically, almost any password can be cracked; thus, even if your password is ‘rdsfe:#;/jwi6;(@6sk’, it could be cracked. When you leave the default password on your Raspberry Pi, everybody knows your password.
Changing your password is therefor needed to secure your Rapsberry Pi. But it is even better to change the password every now and then, this is more of a precautionary feature than actual security.
If someone has cracked it, they have access to what it’s protecting. Changing your password ends their access: So by changing it regularly you limit the time attackers have to do damage.
