Oplon Authenticator introduces an additional layer of security for your online accounts by adding a second verification during login. With this, in addition to your password, you will have to enter a code generated by the Oplon Authenticator app on your phone. This verification code can be generated by the Oplon Authenticator app on your phone, even if there is no network connection. The data remains yours. It does not involve any cloud services or other types of connections. Set up your Authenticator accounts automatically using a QR code. It is a quick and easy process to ensure the correct configuration of codes and supports time-based code generation. You can select the type of code generation that best suits your needs. It stores your sensitive account data in one encrypted place that you can only unlock. You will never again forget your credentials to access the services you are enrolled in. Copy IDs and passwords to your clipboard with a single tap. Oplon Authenticator is also available for iOS. You can then export your data and import it from one platform to another. Unlock your vault with a master password and gain quick access through smartphone biometrics. You can also block screen capture from screenshots and other methods.

SSL Certificate Checker helps you monitor SSL/TLS certificate health for the websites and services you care about. Add one or more targets (hostname + port, default 443), run a check instantly, or scan your whole list in one tap. The app is designed for a quick daily workflow: open, scan, review risk, and act. What you can check: - Expiry date and days left - Status classification: OK, Expiring, Expired, Failed - Issuer and subject - SAN (Subject Alternative Name) - Serial number and signature details - SHA-256 certificate fingerprint - SHA-256 public key fingerprint - Negotiated TLS protocol and cipher suite Key workflows: - Single target check for immediate troubleshooting - Full list scan for regular maintenance - Saved targets and latest results stored locally on device - Optional periodic background checks (can be turned on/off) Built for practical certificate operations: - Quickly identify certificates close to expiration - Compare protocol/cipher negotiation outcomes - Keep a simple watchlist for internal or public endpoints - Generate and review report-style outputs inside the app Security perspective for connected-device teams: - Includes TLS protocol and cipher suite visibility to support baseline security reviews - Helps teams spot weak or unexpected negotiated ciphers during routine checks - Useful as an evidence aid for internal security discussions and release readiness - Designed as a practical checker, not a complete legal/compliance assessment tool Regulatory context note: - In the EU, RED cybersecurity delegated requirements under Directive 2014/53/EU Article 3(3)(d)(e)(f) apply from August 1, 2025 for covered products - This app can support early HTTPS/TLS posture checks, but it does not certify compliance with RED-DA, EN 18031, or any other regulation/standard on its own Privacy and control: - No account is required to start checking - Targets and recent check results are kept locally for your routine usage - Privacy policy and terms are available from within the app Current release focus: - Core SSL/TLS checking flow and result parsing are available - Batch checking and retry flow are available - iOS background checks are best-effort (system-scheduled) - Multilingual UI foundation is integrated; some languages are still being refined This app is suitable for developers, operators, site owners, and anyone who wants a simple way to track certificate validity and TLS configuration from a mobile device.
