I followed the steps for recovery process of stash -:
- Edit the
<Stash installation directory>\bin\setenv.sh file (or setenv.bat on Windows) and add the "-Datlassian.recovery.password=temporarypassword" argument to the JVM_SUPPORT_RECOMMENDED_ARGS property. The property value must be non-blank, and should look like this when you've done that:

Here we are using "temporarypassword", but you should use your own value. - Start Stash.
- Log in to Stash using the 'recovery_admin' username and the temporary password specified in Step 1.
But now I don't know how should I repair the stash configuration.
4) Repair your Stash configuration. We strongly recommend that you do not perform other actions while Stash is in recovery mode.
Please help me in setting up the user name and password of stash.
