Step 6: After hitting recovery, it will start performing the initialization of management services and will start the CLI. Step 4: In this step, we need to boot in single-user mode. If you are doing it properly, below output will be shown. Console port setting are default, you do not need to change anything. Step 1: Connect your Juniper device with your laptop through console.

In this lesson, we will learn how to recover Root Password on Juniper devices. Users who are authenticated via RADIUS/TACACS+ servers will not be affected after a downgrade.Recovering Root Password for Juniper Devices can be done in few simple steps. MD5-hashed encrypted passwords can also be obtained by configuring a plain-text password in any device that is running Junos OS release 12.3 or by looking up the device configuration file. Set system login user test class super-user authentication encrypted-password 'MD5 hashed encrypted password'Д®xample root#set system login user test class super-user authentication encrypted-password вЂњ$1$ABC123вЂќ If the password is hashed to SHA-256, then configure a new root authentication or configure new user credentials with MD5 hashing as shown below: show configuration system root-authenticationД®ncrypted-password вЂњ$1$ABC123вЂќ # SECRET-DATA ># MD5 hashed starts with $1$Д¬heck whether the password is hashed to MD5 (password starts with $1) or SHA-256 (password starts with $5). This is a limitation in Junos OS 12.3 and earlier.Д«efore downgrading to Junos OS release 12.3, make sure to check that the encrypted passwords are stored as MD5 hashed passwords. In SHA-256 hashing, passwords start with $5$:Д®ncrypted-password '$5$ABC123' # SECRET-DATA >#SHA-256 hashed starts with $5$ In Junos OS release 15.1, when a password is configured as plain text, SHA-256 hashing is performed and the password is stored as encrypted text. Root> show configuration system root-authenticationД®ncrypted-password '$1$ABC123.' # SECRET-DATA ># MD5 hashed starts with $1$ In MD5 hashing, passwords start with $1$: root> show version In Junos OS release 12.3 and earlier, when a password is configured as plain text, MD5 hashing is performed and the password is stored as encrypted text. In Junos OS release 17.2 and later images, SHA-512 encryption is used and the password starts with $6$. In Junos OS release 15.1 image, SHA-256 encryption is used and the password starts with $5$. In Junos OS release 12.3 and earlier images, MD5 encryption is used and the password starts with $1$. Therefore, if a password that is encrypted by using SHA-256 in Junos OS release 15.1 is provided to Junos OS releases 12.3 and earlier, the password decryption will fail. This is a limitation in Junos OS release 12.3. In Junos OS release 12.3 and earlier images, encrypting and decrypting of passwords by using SHA-256 is not supported. There is a difference in the way a plain-text password is hashed and stored as encrypted in Junos OS release 15.1 and in release 12.3 and earlier. What are the password hashing and encryption differences between Junos OS releases? This applies to both root and non-root passwords.

When an EX Series switch is downgraded from Junos OS release 15.1 to release 12.3, the SHA-256-hashed password does not work.

This article indicates the difference in hashing or encryption between the two releases, and provides a workaround to make password decryption successful after a downgrade.

When an EX Series switch is downgraded from Junos OS release 15.1 to release 12.3 after implementing any changes, such as root-authentication password change or creation of new users, the password credentials will not work due to a difference in the hashing mechanism used in the two releases.
