node-imap Invalid credentials (Failure)

Good morning,

could you help me, I am not able to connect to the gmail server, below the code.

describe('Check connection to email server', function () {

it('It should return a successful connection message', async function () {

    var config = {
        user: '[email protected]',
        password: 'xxxxxx',
        host: 'imap.gmail.com',
        port: 993,
        tls: true,
    };
    
    async function checkEmailConnection() {
        const imap = new Imap(config);
    
        return new Promise((resolve, reject) => {
            imap.once('ready', () => {
                imap.end();
                resolve('Conexão bem-sucedida com o servidor de e-mail!');
            });
    
            imap.once('error', (error) => {
                reject(`Erro na conexão com o servidor de e-mail: ${error}`);
            });
    
            imap.connect();
        });
    }

    const message = await checkEmailConnection();
})

})

after executing the error is returned thrown: "Erro na conexão com o servidor de e-mail: Error: Invalid credentials (Failure)"

thank you very much

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

@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, '\"'); ^

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?

You need 2FA and App password :)

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?

@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' }, });

@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.
