Password Manager
An app that generates, stores and autofills unique strong passwords for every site.
A password manager solves two problems at once: it makes it easy to have a unique random password everywhere (so a breach at one site doesn't cascade) and it refuses to autofill on the wrong domain (so phishing sites don't get your credentials). Most also store passkeys, 2FA seeds and secure notes.
1Password, Bitwarden, Proton Pass, iCloud Keychain and the Google Password Manager are common options. The single biggest wins are unique passwords per site and enabling autofill so you never type credentials into a spoofed page.
