Key factors to consider

When choosing an authentication method


  • when does authentication become really critical?
  • is there a single most important factor when choosing an authentication method? (hint: users first)
  • is authentication bad for Customer experience?
  • what are the pros and cons of different methods?
  • why is SMS still the most popular delivery method for 2FA?

Authentication made easy

This is how it works

Authentication - How it works

1. User attempts to verify a transaction online.

2. Enterprise submits the number verification request to tyntec. tyntec creates a PIN and sends it via the most appropriate channel (SMS or voice).

3. User receives the PIN and enters the code to verify the transaction.

4. tyntec matches the entered PIN against the passcode sent to the user.

5. Enterprise authorizes/denies the transaction.
