Invalid credentials (Failure) - Gmail about node-imap HOT 12 OPEN

@Vastradamus I was dealing with Invalid credential error but I was able to make it work using App password.An app password is a 16-digit passcode that gives a less secure app or device permission to access your Google Account.
Here is the link how to set up the password https://support.google.com/mail/answer/185833?hl=en
Finally, replace the generated password in the email config password.

I have resolved this error in 2 step:

• IMAP Enabled from "Email Setting"
• Less secure app access Enabled from "Google Account"

Perhaps you need to use the xoauth2 config setting for OAuth 2-based authentication instead of using a password.

from node-imap.

@mscdex I did the configuration, but now it is showing another error:

this is the code
const credentials = {
client_id: 'xxx',
client_secret: 'xxx',
redirect_uri: 'http://localhost',
};

    const oauth2Client = new google.auth.OAuth2(
        credentials.client_id,
        credentials.client_secret,
        credentials.redirect_uri
    );

    const auth = {
        user: '[email protected]',
        xoauth2: oauth2Client,
    };

    const imap = new Imap({
        user: auth.user,
        xoauth2: oauth2Client,
        host: 'imap.gmail.com',
        port: 993,
        tls: true,
        authTimeout: 30000,
        tlsOptions: {servername: 'imap.gmail.com', rejectUnauthorized: false,}
    });

    function openInbox(cb) {
        imap.openBox('INBOX', true, cb);
    }

    async function checkEmailConnection() {
        imap.connect();
    }

    await checkEmailConnection()

this is the error

return str.replace(RE_BACKSLASH, '\\').replace(RE_DBLQUOTE, '\"');
^

same issue

Try to use app password, works for me: https://support.google.com/accounts/answer/185833

Hey all, I seem to have the same problem. Has anyone managed to find a workaround?

from node-imap.

You need 2FA and App password :)

from node-imap.

That's what I tried first, but I was getting this:
Error: No supported authentication method(s) available. Unable to login.

So I assumed I need to use xoauth2. Is there something I'm missing?

from node-imap.

@Vastradamus It worked for me, with 2FA and password

var imap = new Imap({ user: '', password: '', host: 'imap.gmail.com', port: 993, tls: true, authTimeout: 100000, tlsOptions: { rejectUnauthorized: false, servername: 'imap.gmail.com' }, });

I have resolved this error in 2 step:

• IMAP Enabled from "Email Setting"
• Less secure app access Enabled from "Google Account"

This feature appears to have been discontinued by Google.
