Reset jenkins password

gistfile1.txt

0. SSH to server
1. Edit /opt/bitnami/apps/jenkins/jenkins_home/config.xml

2. set userSecurity to false: <userSecurity>false</userSecurity>

3. delete
<authorizationStrategy> and <securityRealm>

4. /etc/init.d/bitnami restart

Now Jenkins should be open:

5. Select Configure Jenkins,
    "Enable Security", 
      "Use Jenkin's own database"
      "Allow users to sign up"

6. Under Authorization, select:  "Matrix-based security"
   and add users and give them all permissions, 
   and remove all permissions from 'anonymous'

One other way would be to manually edit the configuration file for your user (e.g. /var/lib/jenkins/users/username/config.xml) and update the contents of passwordHash:

#jbcrypt:$2a$10$razd3L1aXndFfBNHO95aj.IVrFydsxkcQCcLmujmFQzll3hcUrY7S
Once you have done this, just restart Jenkins and log in using this password:
test

+1. worked like a charm

If you are using Ubuntu 16.04+

Install package --> apt install apache2-utils
After successful installation of the package, execute the below command:

root@localaquaserver:# htpasswd -nbBC 10 admin test123
admin:$2y$10$L76tVpxoxtB.TKB470PmzeFLFivZI8BdRyFv9qMgK9t5dxElnscF6
root@localaquaserver:#

Now add above bcrypt password in config.xml file under default: /var/jenkins_home/ (Container with Image jenkins/jenkins:lts)

Restart Jenkins (based on platform)

1 first check location if you install war or Linux or windows based on that

for example if war under Linux and for admin user

/home/"User_NAME"/.jenkins/users/admin/config.xml

go to this tag after #jbcrypt:

<passwordHash>#jbcrypt:$2a$10$3DzCGLQr2oYXtcot4o0rB.wYi5kth6e45tcPpRFsuYqzLZfn1pcWK</passwordHash>

change this password using use any website for bcrypt hash generator

make sure it start with $2a cause this one jenkens uses it

it worked for me
