## Access Dashboard with HTTPS
* SpringBoot itself has provided the SSL configuration. You can use the project test Keystore:resources/rmqcngkeystore.jks. The store is generated with the following unix keytool commands:
```
#Generate Keystore and add alias rmqcngKey
keytool -genkeypair -alias rmqcngKey -keyalg RSA -validity 3650 -keystore rmqcngkeystore.jks
#View keystore content
keytool -list -v -keystore rmqcngkeystore.jks
#Transfer type as official
keytool -importkeystore -srckeystore rmqcngkeystore.jks -destkeystore rmqcngkeystore.jks -deststoretype pkcs12
```
* Uncomment the following SSL properties in resources/application.properties. restart Dashboard then access with HTTPS.
```
#Set https port
server.port=8443
### SSL setting
server.ssl.key-store=classpath:rmqcngkeystore.jks
server.ssl.key-store-password=rocketmq
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=rmqcngkey
```
## Login/Logout on Dashboard
Access Dashboard with username and password and logout to leave the dashboard。To stage the function on, we need the steps below:
* 1.Turn on the property in resources/application.properties.
```$xslt
# open the login func
rocketmq.config.loginRequired=true
# Directory of ashboard & login user configure file
rocketmq.config.dataPath=/tmp/rocketmq-console/data
```
* 2.Make sure the directory defined in property ${rocketmq.config.dataPath} exists and the file "users.properties" is created under it.
The dashboard system will use the resources/users.properties by default if a customized file is not found。
The format in the content of users.properties:
```$xslt
# This file supports hot change, any change will be auto-reloaded without Console restarting.
# Format: a user per line, username=password[,N] #N is optional, 0 (Normal User); 1 (Admin)
# Define Admin
admin=admin,1
# Define Normal users
user1=user1
user2=user2
```
* 3. Restart Dashboard Application after above configuration setting well.
