Why a password is not enough
A strong password remains useful, but it can be leaked, reused or entered on a convincing phishing page. Multi-factor authentication adds a second check and significantly reduces the value of a stolen password.
Protect accounts that can affect the whole business first: company email, hosting, domains, cloud files, banking services and administrator accounts.
Where passkeys help
Passkeys use a device's security features without asking users to remember or type a shared secret password. This makes theft through fake login pages more difficult and usually simplifies everyday use.
The transition does not need to happen everywhere on the same day. Start with services that support it, with documented backup methods and a clearly assigned recovery owner.
A workable plan
List critical accounts, remove former users, enable MFA and store recovery codes in a controlled location. Then test the device replacement procedure before a real incident occurs.
Technical configuration is only half the work. A short team briefing on phishing, login approvals and reporting suspicious requests makes protection practical.
