For a successful identification you need: - one of the following identity documents: German identity card, residence permit or eID card for EU citizens. - the corresponding ID PIN - an NFC-enabled smartphone This is how identification with our app works step by step: 1. Start the process by entering the 10-digit ident code you can find on your service provider's website into the AUTHADA app. If you do not see an ident code and you are using a PC, go to the website of the service provider you want to identify with a PC and scan the QR code with the AUTHADA app. If you are only using a smartphone (without an additional desktop device), click on the "Start AUTHADA" button on the service provider's website. 2. Now follow the instructions in the app. This includes entering your PIN and reading out your ID card. 3. Then enter the TAN generated in the app on the service provider's website. The ID card PIN You can find your ID card PIN and PUK in your PIN letter, which you received via mail after applying for your ID card. Please note: Before using the online ID card function for the first time, you must change your ID card PIN. To do so, you will need the five-digit transport PIN from your PIN letter. With the AUTHADA app and the "Change PIN" function, you can assign a new, personal, six-digit PIN. In future, you will always need this PIN if you want to use the online ID card function. If you enter your PIN incorrectly three times, your ID card PIN is blocked. With the AUTHADA app, you can unlock your ID card PIN using the "Unlock PIN" function and your PUK. If you have forgotten your PIN or no longer have your PIN letter, you can also have your PIN reset without your PUK at your local Citizens' Registration Office. AUTHADA protects your privacy AUTHADA's eID solution is certified by the German Federal Office for Information Security (BSI) and ensures compliance with the highest security requirements. The smartphone is only used to read out the data for the respective business purpose. Before the read out process, the data to be read out is displayed. Your data is not stored in the app or at AUTHADA - your data is always encrypted and secure. Accessibility We paid attention to accessibility when implementing the app in order to make it accessible to as many people as possible.

HabitTracker turns the daily check-off into something you can see โ€” and that's why it sticks. No account, no cloud, no ads, no subscription. Open the app, tap once, done. Everything else builds up in the background: the streak, the grid, the curve. At a glance, not buried in menus Every habit is a card: check-off circle, current streak, and the running week as a ring. Four of seven done today โ€” that's up top, not two levels down. The wall you don't want to break The detail page holds a full year as a grid of squares. Next to it: longest streak, rate since start, days done. A filled-in year you see; a number you have to interpret. Not every habit is daily Exercise four times a week? Then the week counts, not the single day. "Goal reached ยท +1" instead of a streak that every rest day tears apart. Forgot? Backfill two days Miss a check-off and you catch it up โ€” for today, yesterday, and the day before. No further back, so the streak and rate stay honest. Analytics that give an answer ยท Rate trend over 26 weeks โ€” the direction, not just today's number ยท Momentum โ€” a weighted value of recent weeks, plus the change from last week ยท By weekday โ€” which days work and which don't ยท Connections โ€” "On exercise days you also stretch 86 % of the time, otherwise 77 %" ยท Consistency ranking โ€” every habit sorted, the strongest on top What it costs Two habits are free. A one-time purchase unlocks unlimited โ€” no subscription. Existing habits are never locked.
