Packer vm password gets changed

Packer
1

Hi Team, I’m trying to build resource via packer builders “type”: “azure-arm”, and what is happening that using ssh_password, the existing user password is getting changed and later am unable to ssh into that machine using. Although ssh_username sets the username but it seems password is generated random or getting changed automatically. So, Is it the expected behavior or I am missing something. Please help or consult. Below is the builder section for reference
