Passkeys may be changing authentication, but passwords are not disappearing overnight.
That makes password reuse just as important to address in 2026 as it was years ago.
If the same password protects your email, social media and shopping accounts, one breach can expose all of them.
Use a password manager to create unique passwords for every important service.
Your email account deserves particular attention because it can often be used to reset other accounts.
Where a service supports passkeys, consider using one instead of a password.
The goal is simple: compromise one account should not automatically compromise the rest.
