TOTP Authenticator

TOTP Authenticator keeps your two-factor authentication codes together in a clean, focused interface. Scan a service’s setup QR code, enter its Base32 key or paste an otpauth://totp link. Check the account details before saving. Secret keys stay in protected system storage on your device, and codes work without an internet connection. • Large, easy-to-read codes with a refresh countdown. • Search accounts and copy the current code with one tap. • QR setup and manual entry, with advanced settings kept out of the way. • SHA-1, SHA-256 and SHA-512; 6, 7 or 8 digits; refresh intervals from 15 to 120 seconds for compatible services. • Layouts adapted for phones, tablets, landscape and foldable screens. • System, light and dark themes, remembered between launches. • Confirmation before removing an account. • Best-effort clearing of copied codes after 30 seconds if the clipboard is unchanged. No InetTools account, advertising or cloud sync is required. Camera images are processed on the device and are not saved or uploaded. Account names, secret keys, codes, QR contents and clipboard contents are excluded from analytics. PostHog, AppMetrica and Sentry process limited usage and diagnostic data as described in the privacy policy. This app supports TOTP, not counter-based HOTP or migration QR bundles. Keep recovery codes supplied by each service: the app cannot recover secrets after device loss or data deletion. Removing an account here does not disable two-factor authentication on the original service.

A calmer design with large codes and a clear countdown. Improved QR setup, account search and layouts for tablets and foldable screens. Added confirmation before removal, safer saving and privacy-conscious product analytics. Updated themes and 16 KB compatibility.
