reCAPTCHA erro "BadCredentials', your .env password or email is wrong."

I have spent 15 hours trying over and over to get reCAPTCHA setup. Everything works until clicking on submit and every time the result says Google thinks I’m a bot. I’ve tried everything from changing the User ID to User Password in the .env file and have tied various tagging in the server.js file. Nothing has helped thus far.  This is the message I get over and over "success": false,
    "error": "Invalid login: 535-5.7.8 Username and Password not accepted. For more information, go to\n535 5.7.8  https://support.google.com/mail/?p=BadCredentials a92af1059eb24-1276af2ea06sm10110769c88.7 - gsmtp",
    "tip": "If this says 'BadCredentials', your .env password or email is wrong."
