Anonymous Login

Anonymous is one of the most easiest authentication method available in the market but should be used with causion as it is not a reliable type of authentication for most cases.

 
// let app = await initializeRembaseSync(<appId>,<selfHostUrl>?)
 
async function yourOwnLoginFunction(){
 
let credential = CredentialTypes.anonymous()
let user = await app.login(credential,<authKey>)
 
}
 
 

authKey : (optional) A unique 32 bit key. If you are using self hosted backend you need to pass this field.

authKey is used to verify your users at your custom backend and can be found in .env file.

Email password Login

To use email password login you must register and verify the user first.

Register

let await = app.registerUser(email,password)
 

upon successful registration an email will be sent to the user. You might want to prompt user to check their email and spam

To send verification email again use

app.resendEmail(email,method) // method can be 'token' or 'otp'

A verification email will be sent to User that will look like the following.

https://yourWebsite.com/yourVerificationPage?token=token

Once the user is successfully registered you can continue with the Login

const credential = CredentialTypes.email_password(email,password)
const result = await app.login(credential)

Email OTP Login

You can also sign-in user with thier email and OTP. Here's how you can do it.

Step1. Send the otp to the user's email

 
app.send_email_otp(email)
 

Step2. You can use that OTP and the email to login to the User.

 
const credential = CredentialTypes.email_otp(email)
const result = await app.login(credential)
 

Note: If you are using your own email credentials you might want to prompt users to check their email also.
