The cbreset_password tool is used to reset an administrative or read-only password.

This tool is found in the following locations, depending upon your platform:

To reset the administrative password:

./cbreset_password hostname:port

This will result in output as follows:

Please enter the new administrative password (or <Enter> for system generated password):

Enter a password of six characters or more or you can have the system generate one for you. After you enter a password or accept a generated one, the system will prompt you for confirmation:

Running this command will reset administrative password.
Do you really want to do it? (yes/no)yes

Upon success you will see this output:

Resetting administrative password...
Password for user Administrator was successfully replaced. New password is Uxye76FJ

There are a few possible errors from this command:

{error,<<"The password must be at least six characters.">>}

{error,<<"Failed to reset administrative password. Node is not initialized.">>}

The first one indicates you have not provided a password of adequate length. The second one indicates that Couchbase Server is not yet configured and running.
