Create error message for incorrect email or password (ReactJS, Firebase Auth)

Here is my experience link. [login to view URL] Dear Client, Thanks for taking time on my proposal!! I just read your job posting and it sounds like you need senior Reactjs developer. I’d really like to work with you on this one if possible! I do have a couple of questions, but first I’d like to make you an offer and some background so you can check my work out. I am a full stack developer who has rich experience in web development especially in React, PHP, HTML, CSS, Javascript, Bootstrap, Firebase, Mongo, API development & integration. As an enthusiastic developer who loves coding, I always work on the VCS systems like Github during project development with Project Management Tool such as Jira, and Trello. However, I am looking to get a few clients that I can build upon. If you take a look at my work and feel that I could help you, I’ll do it for a 10% discount. You’ll get all the expected stuff like a great professional service and a fast turn around, at a bit less, and I get a bit more exposure. I have some question and I wanna check the existing site or design in details. If the above offer sounds like something you would be interested in, I’d love to hear from you. Regards,
