I would like to login with mobile number instead of email id since we’ve legacy user data with us and most of them don’t have an email id. We plan to create email ids for each user & update in csv file to upload if required.
-> User enters the mobile no. & pwd.
-> Fetch the relevant email id from the records
-> Validate it.
Can you suggest a workflow to login with mobile no. & pwd. How to fetch a email id with mobile no. & validate it?
