Sending mail using Java Code

Old code which works before 2 step verification was not enabled

Note : if your Gmail has 2 step verification enable then your email password will not work, you need to go to your gmail and go to app password in settings

you can go to ->Manage your google account and select --> security. You could see 2 step verification is ON.

If 2 step verification is ON App password is mandatory, you can see App passwords tab in same page where you see 2 step verifications ON.

click on App Passwords, you will see "Select the app and device you want to generate the app password for."

click on select App drop down , you will see calender, contacts, mail, youtube and others options

click on others then select device dropdown near by.

if you device is available choose that(ipad, windows, mac, etc..) else choose others for custom name.

provide your custom name and click on generate.

Your password must have generated. Use this password for email sending in code where you are asked for password. This app password manages authentications with 2 step verifications.

Thank you,
