Answer 1

just make sure that your database is created. and also if your user is not added in the admin database, then make sure to add it by putting db.createUser( ... {user:'admin',pwd:'admin',roles:['root']} ... )

Answer 2

mongoose.connect("mongodb://[usr]:[pwd]@localhost:[port]/[db]",{ authSource: 'admin', useNewUrlParser: true, useUnifiedTopology: true });

I was getting same error. Resolved by adding authSource option to connect function solved the issue. see above code.

Answer 3

just add ?authSource=yourDB&w=1 to end of db url

 mongoose.connect('mongodb://user:password@host/yourDB?authSource=yourDB&w=1')

this work for me . &w=1 is important

There is many ways to make it work. This is what worked for me [mongoose v5.9.15] :

mongoose.connect('mongodb://localhost:27017/', {
    auth: {
        user:'root',
        password:'example'
    },
    authSource:"admin",
    useUnifiedTopology: true,
    useNewUrlParser: true
}

I have found the solution hier, looks like when you create an user from the mongo shell, it makes SCRAM-SHA-1 instead of MongoDB-CR. So the solution to create a new user with MongoDB-CR authentication.

MongoDB-CR Authentication failed
