Query re editing script for 2FA

[Laura Peaurt]

Hi there,

Apologies that I have tried to understand this but really can't get it...

I use a script to report on contents of specific folders - particularly to get reports on formats and size.

The script taken from James' previously supplied examples (and edited a bit) has worked until recently when I get an error message relating to 2FA.

I presume I need to change the way I input store my password information, but I'm afraid I have no idea how to put this into the code / files.

Just to note we have used 2FA within Preservica for some time now.

Any advice / help appreciated!

Many thanks

Laura

Script used as below from James examples (I have taken out my account details throughout):

from pyPreservica import *

content = ContentAPI()
entity = EntityAPI()

folder = entity.folder("f78fc2a3-6e66-48f9-9527-fa2131806ade")

print(f"Searching inside folder {folder.title}")

if __name__ == '__main__':
    metadata_fields = {
        "xip.reference": "*", "xip.title": "", "xip.description": "", "xip.document_type": "*", "xip.parent_hierarchy": f"{folder.reference}",
        "xip.security_descriptor": "*",
        "xip.identifier": "", "xip.bitstream_names_r_Preservation": "", "xip.format_r_Preservation": "", "xip.size_r_Preservation": ""}


    content.search_callback(content.ReportProgressCallBack())

    content.search_index_filter_csv("%", "assetsinfo.csv", metadata_fields)

.................................................................................................

And then credentials file stored in same folder:

[credentials]
username=[myusername]        
password=[mypassword]
tenant=[ourtenant]
server=[europeserver]

...............................................................................................

Returns following error:

Failed to create a password based authentication token. Check your credentials are correct

Hi

Yes, the way the Preservica API works with systems setup with two factor authentication has recently changed.  

You will need to add a second password to your credentials.properties file, you can find this new password when you turn on two factor authentication for a user.

The process is described here.  You may need to disable 2-FA for the account and then re-enabled it.

Hi James,

Just to belatedly update and say thank you - with this change (and updating my pyPreservica version) this is now working again :-)

Kind regards,

Laura
