This error is saying that your Gmail account does not have the correct security permissions set to allow DRD to send emails on your behalf.
This is fixed by logging into your Gmail account and modifying your account settings. Please see full solution below.
Access your account
To help keep your account secure, we may block these less secure apps from accessing your account, and you’ll see a “Password incorrect” error when trying to sign in. If this is the case, you have two options:
- Upgrade to a more secure app that uses the most up to date security measures. All Google products, like Gmail, use the latest security measures.
- Go to Allow less secure apps and choose “Allow” to let less secure apps access your Google account. We don't recommend this option because it may make it easier for someone to gain access to your account.
If you’re still having issues accessing your account after trying the options above, see other reasons you might receive the"password incorrect" error.
