Is it possible to store credentials?

[zymbuzz]

Hello,
First of all, thank you again for developing this great tool! I had a quick question — is it possible to store credentials for internal APIs? Currently, the tool prompts for credentials each time a dataset is requested.
Kind regards

Hi @zymbuzz, the credentials should be stored already. What tool and what provider are you using?

[zymbuzz]

I am using your SDMX connector for ESCB internal access

[amattioc]

Which language?

[zymbuzz]

I am using Matlab

It's strange actually. The credentials should be retained in memory for the session. MATLAB should ask them only for the first call of every session.

If you make many subsequent calls are you asked for the password every time?

[zymbuzz]

That's right, it does retain in the memory for the session. However, I would like to know if it is possible to avoid ever putting this information in future sessions?

[amattioc]

Ok, clear now. We don't persist credentials, but I can add a new function, like setProviderCredentials that we already have for R. This way you can set the credentials by code and find your way to persist them.

Would this be useful?

[zymbuzz]

If it safely stores credentials for the provider, it would also be beneficial to have it for MATLAB integration. That would be trully appreciated!

[amattioc]

I'm sorry, I was not clear. The function will not store the credentials: it will only set them in advance, so that you'll not be prompted for them. You will have to find your way to store them, according to the rules of your institution.

[zymbuzz]

So if I understand correctly, the function would retrieve credentials that were stored somewhere and then apply them for the connector?

You can write your own logic to retrieve the credentials, and then pass them at MATLAB startup to the setProviderCredentials function to use them in your MATLAB session.

[amattioc]

. This is the signature in R:

setProviderCredentials <- function(provider, user=.jnull(), pw=.jnull())

[zymbuzz]

Now I get it, thanks a lot for clarifying. This would be super useful

Great. Opened issue #287 . It will be fixed soon
