Nifi 1.14 asks for username and password on Windows

Explorer

My environment is testing on Windows 10. I installed version 1.14 and started. The chrome 91.0.4472.124 says it is not secure and I confirm to go to the site "https://localhost:8443/" not secure. The address changes to "https://localhost:8443/nifi/login" and asks for username and password. What username and password should I use? Where can I generate this username and password?

Authenticating

The default configuration generates a random username and password on startup. NiFi writes the generated credentials to the application log located in logs/nifi-app.log under the NiFi installation directory.

The following command can be used to find the generated credentials on operating systems with grep installed:

laptop:nifi-1.0.0-SNAPSHOT myuser$ grep Generated logs/nifi-app*log

NiFi logs the generated credentials as follows:

Generated Username [USERNAME]
Generated Password [PASSWORD]

"

File Explorer > Nifi Folder > "logs" Folder > Edit "nifi-app.log" > Search "Generated Username"

In this video, at 3:01 time, we see username and password is being automatically generated on Nifi 1.14 Linux. On Windows, this doesn't happen. Also, we have "nifi.sh" only for Linux. There is no "nifi.bat" to generate username and password, yet.

Hi @GabrielNifi,

 

I'm not an expert but I did locate a section on windows under "How to install and start NiFi" in the NiFi System Administrator’s Guide. Hopefully it holds the answer for you.

Thanks, but the documentation has not yet been updated to version 1.14.

An additional note for anyone coming here that isn't seeing the Generated Username/Password log entries (for example on Docker), you can set those by running bin/nifi.sh set-single-user-credentials <Username> <Password>.

When I'm trying to set user, password for single user login then its not working.

./nifi.sh set-single-user-credentials admin admin1234567

From within this path: 

 

(change version to your own)

/usr/local/Cellar/nifi/1.15.2/libexec/

 

Be sure to have it as follows:

bin/nifi.sh set-single-user-credentials "admin" "admin1234567"
