@Swarnendu0123 can you please review this PR?

I have mentioned it multiple times that we are going to use firebase for authentication. We don't need this.

[ManpreetSingh18]

@Swarnendu0123 I mentioned it before getting it assigned and you assigned it after my message stating the same Mongo db is mentioned in issue and also in the issue itself mongo db is mentioned . Additionally, the documentation includes MongoDB as well.

[Swarnendu0123]

We will be using mongodb but not for the authentication. We will be using mongodb to store generated links and qrs. We will not store mongodb to store users.

@Swarnendu0123 ok, I will use Firebase. Now I am supposed to do everything mentioned in issue but in Firebase please check the video. You want that type of work in Firebase. Please confirm same?

[Swarnendu0123]

I am planning to use the authentication service provided by firebase in this.
