Opt for TOTP to Deal With MFA App Sprawl

The document offers practical guidance on reducing reliance on vendor-specific MFA apps by adopting TOTP-based authentication, explaining how TOTP works and its benefits for portability, offline/online backups, and multi-device setups. It provides tips to identify whether a service supports TOTP (e.g., references to Google Authenticator or “try another method”) and outlines considerations when choosing a TOTP app, including backup options, device registrations, and auditability. The piece emphasizes standardization and resilience planning rather than detailing any specific security incident or threat activity.
