What is the default username and password for Grafana login page?

By looking up the docs we can find that the magic combo is admin as username and admin as password.

However if you changed some configuration file you should be able to find it there. The default config file can be found here: $WORKING_DIR/conf/defaults.ini and can be overridden using the --config parameter

The item in the config you're looking for should be in the section:

[security]
admin_user = admin
admin_password = admin

Default password for grafana is "admin" for admin user. you can change the same on setting.

default grafana login is

username: admin
password: admin

here is a linux tutorial on how to reset grafana admin password if you lost it https://codesposts.com/Wg04jK59

I had the same problem. I changed the password after the first login and then forgot what it was. However, I was able to fix it by using the grafana-CLI through the docker container. At the command line:

docker exec -it <name of grafana container> grafana-cli admin reset-admin-password <fill in password>

This resets the admin password back to "admin". When you log in to grafana again, you will be prompted to change the password to something better.

Default credentials for Grafana

username: admin
password: admin

If you are using Prometheus Operator then user/pass is:

user: admin
pass: prom-operator

Install prometheus-operator using helm:

#helm3
helm repo add stable https://kubernetes-charts.storage.googleapis.com


helm install my-prometheus-operator stable/prometheus-operator

In K8s, to get user/pass of grafana pod, do the following

Get pods and find out what's the name of grafana pod

kubectl get pod

Describe grafana pod:

kubectl describe pod my-release-grafana-7f59ddb678-r4jq4

Or simple in one command (if you deployed it in helm chart)

kubectl get pods --namespace default -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=my-release"

The output should look like the following:

...
Environment:
GF_SECURITY_ADMIN_USER:      <set to the key 'admin-user' in secret 'my-release-grafana'>      Optional: false
GF_SECURITY_ADMIN_PASSWORD:  <set to the key 'admin-password' in secret 'my-release-grafana'>  Optional: false
...

get user name and password from secret:

kubectl get secret my-release-grafana -oyaml

this should give you something similar to the following output:

apiVersion: v1
data:
admin-password: T1lsV0ZPY2liM05Ceml5cVZkVmk3N1ZqWWtrS0phU3Jjdm9sMTNkWA==
admin-user: YWRtaW4=
ldap-toml: ""
kind: Secret
metadata:
annotations:
meta.helm.sh/release-name: my-release
meta.helm.sh/release-namespace: default
creationTimestamp: "2021-08-11T20:12:34Z"
labels:
app.kubernetes.io/instance: my-release
app.kubernetes.io/managed-by: Helm
app.kubernetes.io/name: grafana
app.kubernetes.io/version: 8.1.0
helm.sh/chart: grafana-6.15.0
name: my-release-grafana
namespace: default
resourceVersion: "842508"
uid: 3d3326fb-a7c8-4382-9abc-8ffd2f4d7a11
type: Opaque

decode user name and password

echo "T1lsV0ZPY2liM05Ceml5cVZkVmk3N1ZqWWtrS0phU3Jjdm9sMTNkWA==" | base64 --decode

The easiest thing is reset the password, if you don't have docker installed in your cluster you can use kubectl

kubectl exec -it <name of your pods> -n <name of your namespace> grafana-cli admin reset-admin-password <your reset password>

so it will look like this

kubectl exec -it grafna-haks1k2-628181 -n my-grafana grafana-cli admin reset-admin-password admin

remember: when you don't have a specific namespace in your cluster for Grafana you can remove -n my-grafana.

good luck

With grafana-5.1.4chart the user name is admin and the password is password :)

kubectl get secret --namespace $NAMESPACE grafana \
-o jsonpath="{.data.admin-password}" | base64 --decode ; echo

Check your Docker Compose for this:

environment:
- GF_SECURITY_ADMIN_PASSWORD=\{\{YOUR-PASS-WILL-BE-HERE}}
