ServerDoor allows you to use your smartphone like a secure door for remote access to your personal server. A user-friendly session manager with a simple and intuitive interface, a full-featured terminal emulator that supports gesture control, as well as a tool for working with SSH keys - now all those thing can be placed in your pocket. Connect to your servers with using telnet and ssh protocols to administrate them in any situation anytime. Main advantages and functions: -The tool for working with SSH keys allows you to generate them, as well as to import and export them. RSA, DSA, EC, ED25519 keys are supported, and the openssh-key-v1 format is used to store them. -Thanks to the built-in password manager, you do not have to keep in mind the passwords for each server and key. The password database is stored on the device and encrypted with AES256-CBC using the master key. You can manage the password manager or disable it altogether in the settings. -Snippets system will be useful for advanced shell admins and can be used for make scripts those you can call from terminal session anytime. -Export and import app data features allows you exchange data between different devices or make backups anytime. -Convenient gesture control makes it possible to change the font size in the terminal by simply stretching instead of constantly switching to settings, and sticky scrolling allows you to quickly navigate even in the most voluminous sessions. • Advanced terminal emulator, supports most ESC sequences, SGR and utf8 encoding. • Additional keyboard and hot buttons, allow you to use most commands and keyboard shortcuts, as well as emulate mouse clicks in terminal applications. -Supports simultaneous operation of an unlimited number of running sessions, including in the background, when the application is minimized. -The ability to manually set a limit on the number of lines stored for each session (or disable the limit altogether), allows you to flexibly configure the device's memory consumption by running sessions. Whether you want to store the whole session or set a hard limit to save memory is up to you. -To save memory, session data is compressed and stored in a fragmented way, which allows you to turn off the limit and store even the most voluminous sessions without large buffer allocation errors. Tired of Telnet clients cutting HTTP responses without even allowing you to view the header? Then this app is for you!

Someone reached out to you claiming to be a celebrity, an athlete, a public figure, or someone known to the public. Before you reply, before you do anything they ask: why not check if it's really them? That is what AuthentiKate is for. Impersonation scams are not new, and they are not slowing down. Someone uses a famous person's name, photo, and reputation to earn your trust โ then they use that trust to cause harm. They ask for money, personal information, or access to things you would never give a stranger. The harm is real. We built AuthentiKate because there was no simple, reliable way for an ordinary person to know for certain who they were talking to. Now there is. HOW IT WORKS Search the name of the person who contacted you. Select the channel โ social media, phone, email โ and then ask that person to send you a verification code. Every verified figure on AuthentiKate has been identity-confirmed before their account is activated. When they need to prove their identity, they open the AuthentiKate Verified companion app and generate a 6-digit code. It can only come from their verified device. You enter it here. If it passes, it is them. There is no other way to get a passing code. Nothing to screenshot, nothing to reuse, nothing a scammer can replicate. If the code passes, you see the person's verified title and their public profile links, the information they chose to share with the world. That is the first time any of that information appears. Before a valid code, you see their name and nothing else. If the code does not pass, you get one clear result: we could not verify this person or contact. ACCESS TO USE (with no hidden agenda) AuthentiKate is open to everyone. No account. No sign-up. No tracking. We do not collect your personal information, store your searches, or sell your data. Your verification history stays on your device and goes nowhere else. WHAT MAKES THIS DIFFERENT FROM A VERIFIED BADGE A verified badge on a social platform tells you that platform approved that account at some point. It does not tell you who is sitting behind the screen right now, in this conversation, today. AuthentiKate uses a live code that can only be generated by the real, verified person at the moment you ask for it. A badge can be bought and copied onto a lookalike account. An on-demand verification cannot. OTHER THINGS TO KNOW If the person you are trying to verify is not yet in our directory, you can recommend we reach out to them. We are grateful for every recommendation and will do our best to bring them aboard! If something feels off or strange about a conversation even before you check, trust your instincts. AuthentiKate can help confirm if a public figure is who they say they are, but your own judgment is also a powerful tool. If you can't verify someone and believe you have encountered an impostor, report them directly in the app. We do our best to share these alerts with the public figures themselves.

Verdict
The clearest difference is in-app purchases: AuthentiKate at none against ServerDoor's 1. AuthentiKate also leads on device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.
