ipatool periodically losing iTunes Store authentication

[gitevedev]

What happened?

is it an expected behavior for ipatool to lose authentication, and require to re-auth into iTunes store again after some time (even though it had been signed into iTunes Store previously and auth was never revoked manually)?

DBG error="received error: Sign In to the iTunes Store" metadata={"Data":{"CustomerMessage":"Sign In to the iTunes Store","FailureType":"2042","Items":null}, ...

if it is, is there any way to automate re-signin (considering 2FA is normally required when signing in?)
Is it known under which circumstances does the auth token expire (is there a specific timeout after the last sign in, or is there a timeout after last time being used to download a bundle?)

Version

2.2.0

This is completely controlled by the cookie returned by the App Store API. You will have to authenticate again periodically but afaik a 2FA will not be needed every time.

Thanks for your reply.

But why isipatool unable to re-authenticate automatically, considering it stores both login and password in ipatool-auth.service keychain entry?
Is there a way to instruct ipatool to use these credentials instead of needing to type them manually everytime the sign in fails again?

I am asking because we use this tool for automated tests and it makes it burdensome to re-login manually on test machines once the passwordToken becomes invalid (which happens every now and then).

Thank you.
