Buy hardware keys for every admin, today
+ Why it matters - Why it matters
Order two FIDO2/WebAuthn hardware keys per admin. One primary, one backup kept somewhere safe. While the keys ship, enroll device passkeys on the same accounts so you're not waiting to start. Enroll the keys on your identity provider first, then source control, then your cloud's root account, then any other crown-jewel SaaS. Disable SMS and push as fallback factors once keys are working. Leaving them on means an attacker can downgrade to the weakest one. YubiKey 5 NFC is the common choice (around $50 each), but any FIDO2-certified key works.
