New research from IBM Security has found that people value security more than convenience when it comes to managing their digital lives today, but "password hygiene" — the habit of using unique, complex passwords to protect each of those accounts — is still relatively lax among millennials.

According to the study, which surveyed about 4,000 adults in the United States, the E.U. and Asia-Pacific regions in October and November, 75% of millennials said they're comfortable using biometric authentication, compared to just 58% of those 55 and older. But just 42% of millennials use complex passwords, compared to 49% for the 55-and-over set, and they maintain fewer unique passwords.

"Older adults displayed better habits when it came to password creation, yet younger generations were more inclined to adopt password managers, biometrics and multifactor authentication as a way to secure their online accounts. This could be an indication that younger generations have less confidence in passwords and are instead looking to alternative methods to secure their accounts," the study noted.
