I am making an application with Flutter and in this application I want to login with integer-value-password that I have saved in database instead of email-password login. I guess there is no such login form in Authentication. So where do I save this integer value?
As an example, a student will log into the system with their school number and password.

You should write your backend API for this, for example with cloud functions that read/write from your database.

Is there anyway to code and have the app recognize people by their device?
Firebase provides an anonymous login feature. You can read more about it here:
https://firebase.google.com/docs/auth/ios/anonymous-auth
Also, if you choose to include a sign in feature later, you can convert the anonymous account into a permanent account while keeping their data.

I am creating a health clinic and portal application in cakephp. I need to insert encrypted data in database not using base64 encode and decode method and to use in search also. Can someone help me by providing their valuable suggestion.
Have a look at the Cookbook under Models > Callback Methods.
http://book.cakephp.org/2.0/en/models/callback-methods.html
Maybe you need to use beforeSave and afterFind?
You could use beforeSave to encrypt data before it hits the database, and afterFind to decrypt it between the database and controller.
