In this comprehensive guide, we will walk you through the process of finding the username and password for a Virtualbox Ubuntu image. This is a common issue that users face when they download and install a preconfigured Virtualbox Ubuntu image and are not provided with the login credentials.
The default username and password for most Virtualbox Ubuntu images are typically "ubuntu" and "ubuntu" respectively. However, if these credentials don’t work, you can try checking the image source for provided login details or using common default credentials like "root/root", "admin/admin", or "user/user". If all else fails, you can reset the password using Ubuntu’s recovery mode.

Default Username and Password
The default username and password for most Ubuntu images are typically “ubuntu” and “ubuntu” respectively. However, this might not always be the case. If you’re unable to login with these credentials, it might be possible that the image provider has set different login details.
How to Find the Username and Password
Here are a few steps you can try to retrieve or reset the login credentials:
1. Check the Image Source
The first place to check is the source from where you downloaded the Ubuntu image. Most providers mention the default username and password on their download page or in a README file.
2. Try Common Default Credentials
If the credentials aren’t provided, you can try some common defaults. Along with “ubuntu” as both username and password, other common combinations include:
- Username: “root” Password: “root”
- Username: “admin” Password: “admin”
- Username: “user” Password: “user”
3. Reset Password using Recovery Mode
If the above methods don’t work, you can reset the password using Ubuntu’s recovery mode. Here’s how:
- Start your Virtualbox machine and hold down the Shift key to get the grub menu.
- Select ‘Advanced options for Ubuntu’ and then ‘Ubuntu, with Linux … (recovery mode)’.
- In the next menu, select ‘root Drop to root shell prompt’.
- At the root shell prompt, type in
passwd <username>and press Enter. Replace<username>with the username for which you want to change the password. - You will be prompted to enter a new password and confirm it.
- Once done, type
exitand press Enter to reboot the machine.
Please note that this method requires you to know the username. If you don’t, you can list all users by typing ls /home in the root shell prompt.
