Auto-login not persisting token when AZCOPY_AUTO_LOGIN_TYPE=DEVICE

[sean-jost]

Which version of the AzCopy was used?

10.20.1

Which platform are you using? (ex: Windows, Mac, Linux)

Linux

What command did you run?

export AZCOPY_AUTO_LOGIN_TYPE=DEVICE
export AZCOPY_TENANT_ID=tenant id
... multiple azcopy commands

What problem was encountered?

Have to enter code into web browser for every azcopy command encountered a script. Not a usable solution when there many commands.

How can we reproduce the problem in the simplest way?

Should be easy to reproduce. It appears from the code that auto-login disables token persistence altogether.

Have you found a mitigation/solution?

Don't use auto-login, use azcopy login instead, but it's getting removed in 10.22.

Azure CLI persists tokens in ~/.azure folder; could azcopy do the same?
