22 rules for designing sign up & sign in journeys
Sign-in/up journeys have been there ever since the transactional ecommerce begin. But, after 20 years, we still tend to get that wrong. Most of the time, these are dictated by the platform of choice or the UX preference. Debates rage on, in the interweb, on whether a decision by an organization is correct, user friendly and complies with security practices.
The sign-in/sign up step is a big hurdle the user has to cross to enjoy the services you are offering. A bad SI/SU journey leads to large drop-offs and poor experience.

Rule 3 — Indicate password policy, but only stop the common ones
The rule should be to indicate the strength of the password, but if the password doesn’t fall into the common category, don’t stop the user from signing up. The rationale is simple — if they have to come up with a new password, they’ll most likely forget it and the next time they want…
