manual sending of OTP

Hi, is there any way to custom integrate sending otp to the users

As with anything custom, you can use an Appwrite Function and use any provider you want

but how can get the number otp generated by appwrite?

If you want to implement a custom OTP function, you can use this as something to start with:

• Create a function that takes the userId as an input.
• In this function, generate a random 6-digit number
• Assign this 6-digit number to the user with user prefs

Pretty straight-forward

and then how to create session?
