Email Verification

Before the user signs up (i.e. creates an Identities::User), we verify their email within the sign up form.

• User inputs email
• User clicks verify email
  • OTP field appears
• System sends OTP
• User receives OTP
• User inputs OTP into the OTP field
• User clicks verify

This process requires us to store name@email.com: 123456 key-value pair in temporary storage.

• We store this in Redis, since it's fast.

Generate OTP Rules

• Email
  • valid email format with valid_email2 gem
• Identities::Users::EmailVerification
  • if exists, ensure it is within resend window
  • if not exists, send the OTP
