How to Change a Password in Linux

In this guide, we’ll cover how to change a password in Linux using the passwd command followed by the name of the desired user. This method can be used to change the password for the root user as well as for individual users.

*Note: before changing any passwords, it is advised that you write down any pre-existing passwords as well as any new passwords you intend to create into a notepad file or store them in a password management software where they can be accessed as needed.

 

Resetting the Root Password

In order to reset the root password of a Linux server, follow these steps below.

  1. Log in to the server with the root user using your existing password
     
  2. Now, to change the password for the root user, enter the command:
     
    passwd root

  3. On the new password prompt, provide the new password a couple of times and then hit enter.
     
  4. The root user’s password has now been changed.

 

Changing Passwords in Linux for Non-root Users

As in the example above, to change a password in Linux for anyone other than the root user, you can use the passwd command followed by the name of the intended user.

For example, let’s say you have a user named “user_1” and you need to change their password. To do so, you would use the following command:

passwd user_1

Same as in the process outlined above, once the command has been entered, you will be prompted to enter a new password for this user. After typing in the new password, hit enter to finalize the changes.

Rapid Restore

Backup your entire server’s data every night and have access to 5 days of rolling restore points.  Restore your server’s data, OS and configuration any time you need it.

Our Rapid Restore service saves the day during accidental data loss, hardware failures and virus contraction. Simply pick your recovery point and restore the data from that day. 

DDoS Protection

While our competitors may advertise DDoS protection, most often, they are merely implementing easily evaded router rules or simply black-holing targeted servers. They consider this “DDoS protecting their network.” However, neither of these solutions should give comfort to any online business. Should your site be attacked, chances are likely both of these options will end with your server being taken offline. At Hivelocity, we take the responsibility of keeping your servers online very seriously. For this reason, we offer two very serious forms of DDoS protection.

FREE

Every solution we provide includes our Filtering Edge of Network System (FENS). FENS is a series of proprietary systems that proactively monitors and protects the entire Hivelocity Network from most common Denial of Service (DOS) and Distributed Denial of Service (DDoS) attacks.

$15/MONTH PER SERVER

For an extra fee, you can enhance your server’s protection further with the addition of our Server Defense System. Our Server Defense System sits in front of your server, inspecting inbound data and looking for malicious traffic. The moment an attack is detected, it instantly begins scrubbing each data packet. Hivelocity’s Server Defense System delivers business continuity even in the face of massive and complex attacks.

Our Server Defense System is like adding an alarm and armed guard to your business, alerting you to and destroying anything attempting to jump that fence. Our Server Defense System utilizes internally developed proprietary systems in addition to Corero’s Threat Defense Smartwalls for data packet scrubbing. Each of our data centers is a scrubbing center with Corero Smartwalls on-premise, allowing us to provide on-prem zero-lag data scrubbing.

SSL Certificates

The security of your online commerce and protecting your customers’ data is as important to us as it is to you. When your customers see the green bar, they will know their connection to you is protected. We offer single domain, multi-domain, and wild-card certificates.

We offer industry leading 128-bit encryption certificates, allowing you to conduct e-commerce with complete security. Inspire confidence in your customers by displaying any number of seals and indicators certifying that your site is secure.

Load Balancing

Adding this service to two servers with identical content will allow you to distribute your load evenly across your hardware. Don’t lose business because you couldn’t handle the demand. Load balance and handle your biggest resource spikes with ease.

Firewalls

Stop attacks, prevent unauthorized access, and achieve regulatory compliance. Our Juniper hardware firewalls offload the work so your server never has to consume resources protecting itself from malicious traffic. A single firewall can be used to protect multiple servers.

Cloud Storage

Cloud storage offers users redundancy and easy accessibility, ensuring your data remains secure and readily available. Scale to as much as you need for only a 20¢/GB.

Cloud Storage is distributed and replicated across many servers, protecting your data from hardware failure. Highly scalable, it can handle thousands of client connections via TCP/IP. Connect to your virtual drive with SFTP, FTP, and SSHMount and in the future NFS and AFP. Cloud Storage is based on a stackable design which is upgradeable up to 2TB per instance.
