Verification codes weren't designed for today's customer experience.
For over 20 years we've relied on six-digit codes. Instead of asking customers to type six digits, simply ask them to approve.
Expensive
Per-message SMS costs scale with every login and transaction.
Poor experience
Customers switch apps to copy and paste six digits.
SMS phishing
Anonymous short codes are trivial to spoof.
Lower completion
Every extra step drops conversion and revenue.
Anonymous senders
There's no way to know a code is really from your brand.
Support burden
Undelivered codes drive costly customer service calls.
Stop paying for every verification code.
Every SMS verification message costs money. As authentication traffic grows, your SMS bill grows. Assure dramatically reduces verification costs by replacing SMS with trusted conversations.
