Enable the open source console
Enabling the open source console restarts the Nacos cluster. During the restart, the cluster nodes restart sequentially. This process may generate a small number of logs that indicate client request failures or reconnections. Perform this operation during off-peak hours.
If RAM authentication is enabled, the open source console cannot access data in the MSE registry.
Log on to the MSE console, and select a region in the top navigation bar.
In the left-side navigation pane, choose Microservices Registry > Instances.
On the Instances page, click the name of the instance.
In the navigation pane on the left, click Parameter Settings. On the Parameter Settings page, click Edit, select Yes for ConsoleUIEnabled, and then click Save And Restart Instance to enable the open source console.

Reset the open source console password
Nacos 3.x versions have the authentication feature enabled by default. The default username is nacos. You must reset the password before you can use the console. To reset the password, perform the following steps:
Log on to the MSE console, and select a region in the top navigation bar.
In the left-side navigation pane, choose Microservices Registry > Instances.
On the Instances page, click the name of the instance.
On the Basic Information page of the target instance, click Reset. In the confirmation dialog box that appears, click Reset again.
After the password is reset, copy the open source console password, save it in a secure location, and then close the window. Do not click Reset again.
ImportantYou must save the password because you cannot view it again after you close the window. If you lose the password, you can reset it.
