OpenTodoList is a todo list and note taking application. Organize todo lists, notes and images in libraries, which can be stored either completely local on the device you are working on (and hence ensure no information leaks out to untrusted third parties) or use the built in synchronization features which allows you to synchronize your libraries across devices using your self-hosted NextCloud or ownCloud server, other WebDAV servers or Dropbox. In addition, a library is just a directory holding the items of your library as simple files - this allows you to use any kind of third party synchronization tool to sync your information.

QuickSignOn

Read full description

QuickSignOn streamlines website and app logins while maintaining robust security, strong user privacy protection, and an enhanced user experience. The application's innovative implementation of cryptographic user identifiers effectively mitigates common authentication vulnerabilities and privacy concerns. By replacing traditional usernames and passwords with public-key digital signature-based authentication and privacy protection protocols, QuickSignOn offers significantly stronger security than password-based systems. QuickSignOn provides seamless single-tap registration, sign-in, and expedited checkout processes similar to those found in the ReadySignOn iOS app. The solution delivers superior convenience and security compared to standard password managers and token generators. Key benefits for individual users include: • A secure vault that is thoroughly encrypted using AES256 encryption. All metadata, including tags, icons, images, and management data, are protected to ensure complete information confidentiality. • Compatibility with the award-winning, open-source KeePass desktop password manager through a free, open-source plugin. • Exported records are protected with AES encryption using a 1,000,000 PBKDF2 key derivation count to defend against advanced offline attacks. • ReadyTicket functionality expedites and authorizes login requests from any online device. • Explicit user consent is required before any information is extracted from the application. No automatic data synchronization or unauthorized cloud backups occur; all functions can operate without network connectivity except for remote authentication approval. • A dedicated full-screen keyboard facilitates secure and convenient entry of lengthy passphrases. • Built and tested with a reliable data engine capable of managing thousands of records with consistent performance and integrity. • Advanced filters, indexing, and deep search capabilities support enterprise users needing efficient access to extensive record sets. • Automated password generation based on specified length and composition criteria. • A custom password inspector offers clarity, reducing the risk of account lockouts due to input errors. • Options to specify ReadyTicket length and refresh intervals. • Manual ReadyTicket refresh available via tap. • Remote authentication approvals conducted securely with ReadyTicket.
