TOTP Manager review
A focused, free desktop tool for offline TOTP generation and local storage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TOTP Manager is a free, open-source desktop authenticator for people who want to generate and store time-based one-time passwords without relying on an online service. It runs on Windows, macOS, and Linux, with downloads for both Intel and Apple Silicon Macs. The app generates six-digit TOTP codes that refresh every 30 seconds and keeps secret keys on the local machine.
Its workflow is focused and practical for a small personal collection of accounts. Users can import TOTP secrets from JSON files, search entries by label, sort them alphabetically in ascending or descending order, and copy codes to the clipboard. The offline design means secrets are not sent over the network, while the free open-source pricing model avoids paid tiers or recurring plan decisions. This makes TOTP Manager a fit for users who prefer a desktop-only tool with a narrow feature set and local control.
The main trade-off is its security and ecosystem scope. Secrets are stored in localStorage as plain text, with no encryption at rest, encrypted backup, or multi-device synchronization. The application also supports TOTP rather than HOTP and does not provide mobile support, push approvals, or team administration. Choose TOTP Manager if offline desktop access, local storage, and a simple interface are the priorities. Users who need encrypted recovery, synchronized access across devices, mobile authentication, HOTP, or team controls should choose a broader authenticator instead.
