Phone OTP login via SMS, one-tap Google and Apple social login, and OTP verification at checkout.

Passwords kill conversions. OTP+ swaps them for phone OTP login via SMS or WhatsApp plus one-tap Google and Apple social login. Customer login and signup take seconds: no passwords, no resets, no abandoned carts. Add phone OTP verification at checkout to confirm real shoppers and cut fake orders, RTO and chargebacks on COD. Page lock hides B2B, wholesale and VIP pages and collections behind login, so only verified customers get in. Login logs and bot alerts keep you updated on every theme.

Phone numbers with extensions were getting rejected. Support enabled an automatic extension stripper that removes everything after ext, x, or # before validating. Customers can now enter their full phone number naturally and the system handles the cleanup. Small formatting issue with a clean fix.

Expected 10x traffic for a popup sale and asked about SMS throughput. Support pre-scaled our SMS allocation for the sale window and monitored it live during the first hour. Zero delivery delays during peak traffic. The proactive scaling was something I didn't know to ask for.

Our support team couldn't access customer accounts because of OTP blocking them. Support configured a support agent bypass using specific IP ranges from our office network. Agents can log into customer accounts for troubleshooting while the OTP protection stays active for everyone else.
