Blynk Server Block registration

Hi !
I am working with a Raspberry pi 3 and Blynk Server (0.39.8), it’s working perfectly but I’d like to know if it what possible to block user registration. I already have my user account created and I won’t create new ones. I want to do this as I am afraid someone could create one if he has my IP. (tell me if i’m stressing for nothing :wink: )
I’ve opened the app port on my box as I need it to be.
Sorry if my English isn’t perfect !


YES, you can block it. Just follow the “manual” in file :slight_smile:

Thank you very much !

I’m sorry, but I didn’t understand the answer:

Just follow the “manual” in file

I checked the example file and didn’t see anything to help.

Could you provide more details?


I had difficulty at first finding the same file, here are my mini instructions.

create a server.cfg file and add these lines (edit to your settings)

start the server with the new config

java -jar server-0.41.2.jar -serverConfig server.cfg

login to the admin console using the username and password you entered in the server config.

navigate to Config >
pull copy/paste all the stuff you want to change, add the lines you want to change to the server.cfg file.

These arent perfect instructions, but they work for me when i setup my local server.

Does this operation prevent a random user from registering their Blynk project with my local server?

oops i read the question wrong (apologies), been a long day. I see what you’re trying to do, find the setting that locks out new users from creating an account.

looking still.

try this .,

Oops… i fubbed again… Batting zero for the night.

So, basically no options in the Local Server to restrict users, only via whatever security you set on your router/network.

What the future will bring is still undetermined, but marking this solved as it at least shows an answer.

No longer supported and was removed.

Wow, thanks for info. So now my server is “open” to everyone?.. Still no new, unknown users though.

Only if you let us know your Public IP and port :stuck_out_tongue_winking_eye: You can share it here, I won’t tell anyone :innocent:


Sure, I bet you won’t :wink: Same for me - I won’t tell/share anyone :stuck_out_tongue:

I’ve found, that a kind of “workaround” might be the settings. It will allow to create account, but this will be useless.


Good solution! :+1:
