Answer 1

You need the usermod command:

usermod -e -1 $USER

Where -1 serves as the argument to -e.

To remove the expire date.

The expiration date parameter can be empty. (but not missing when the -e option is used) The -e, --expiredate EXPIRE_DATE option is described as follows in man 8 usermod:

An empty EXPIRE_DATE argument will disable the expiration of the account.

The issue being on how you interpret "empty". Both forms, -e or --expiredate= will accept an empty argument. Those being:

  -e ''

or

  --expiredate=
