Yubico Authenticator vs DB48X

Store your unique credentials on a hardware-backed security key and take it wherever you go from mobile to desktop. No more storing sensitive secrets on your mobile phone, leaving your account vulnerable to takeovers. With the Yubico Authenticator you can raise the bar for security. * The Yubico Authenticator will work with any USB, Lightning, or NFC-enabled YubiKeys. * As iPads do not have NFC, they will only work through a Lightning or USB connection. The Yubico Authenticator generates a code used to verify your identity as you are logging into various services. No connectivity needed! Features include: Touch or NFC Authentication - Touch the YubiKey sensor or simply tap a YubiKey with NFC to a mobile phone that is NFC-enabled to store your credential on the YubiKey USB-C support - Connect the YubiKey 5Ci or any USB-C type YubiKey. When prompted, depending on the key, touch the contacts on the sides of the key or the golden ring on the top Biometric support - Experience greater convenience by unlocking your YubiKey with FaceID or TouchID Easy Setup - QR codes available from the services you wish to protect with strong authentication User Presence - New codes generated with just a touch or NFC tap of the YubiKey Compatible - Secure all the services currently compatible with other Authenticator apps Secure - Hardware-backed strong two-factor authentication with secret stored on the YubiKey, not on the mobile device Versatile - Support for multiple work and personal accounts Portable - Get the same set of codes across our other Yubico Authenticator apps for desktops as well as for all leading mobile platforms Flexible - Support for time-based and counter-based code generation Smart Card - Support for Apple's CryptoTokenKit Extension making it possible to use certificates stored on your YubiKey to authenticate with other apps and sites Experience security the modern way with the Yubico Authenticator.

DB48X is a new high-precision scientific calculator inspired by the legendary HP48 series from Hewlett-Packard. It is not an emulator, but a redesign from scratch, which is faster, and delivers never seen before capabilities like computations in arbitrary precision. Like the original HP48, DB48X supports an unlimited stack, RPN and algebraic operations, complex numbers, based numbers, vectors, matrices, text, symbolic computations, numerical solving and integration, graphing and plotting, statistics, engineering units, and well over 1000 built-in functions. DB48X adds several HP50G capabilities, including a library of equations and constants covering mathematics, physics or chemistry. Using modern technologies, DB48X goes well beyond the original HP48 in many ways: - It is significantly faster, uses less memory, and features a higher-resolution 240x400 pixels graphical display. - Integer and decimal values can have an arbitrarily large number of digits, so you can compute log(pi) with 200 digits in a few keystrokes. - The six function keys feature up to three function per key, giving quick access to up to 18 related functions at a time. - Complex numbers can mix and match polar and rectangular form. - Symbolic operations extend to complex numbers, vectors and matrices. - Based numbers can be in any base from 2 to 36, and support any number of bits, making it easy to emulate a 23-bit or 512-bit processor. - Text is represented using Unicode instead of the proprietary HP encoding, facilitating data exchange with the rest of the world. - Multiple graphs can be distinguished using bitmap patterns (DB50X adds the ability to use colors) - Engineering units include all the modern evolutions of the SI system, and can be configured by the user, e.g. to integrate currency units with the exchange rate du jour. Converting between USD/hour and EUR/day has never been so easy! - A built-in hyperlinked help system documents functions simply by holding the corresponding key, and combine a quick start guide, a user manual and a reference manual. DB48X will run many user RPL programs as is. However, since it is not an emulator, it will not run any HP binary object, and notably will not run HP48 games or anything involving system RPL. DB48X is part of a family of compatible RPL calculators that include the free DB40X and the color DB50X.
