How to automate the Lastpass CLI login process

Question

I was wondering if anyone successfully automated the LastPass CLI login process. I cannot seem to get around the password prompt, which I need to automate to make it useful.

I've tried commands like

echo <password> | lpass login <username>

or

yes <password> | lpass login <username>

I keep getting output saying the password is not correct. Has anyone automated this?

Thanks!

You would probably need to disable the pinetry password prompt so that lpass reads your password from standard input.

As the man pages say:

If pinentry program is unavailable, or if the LPASS_DISABLE_PINENTRY environment variable is set to 1, passwords will be read from standard input and a prompt will be displayed on standard error.

Meaning: It should work if you run it like this:

echo <password> | LPASS_DISABLE_PINENTRY=1 lpass login <username>

Or by just setting the environment variable for your shell (export LPASS_DISABLE_PINENTRY=1 in your ~/.profile or similar)
