Why Biometric Identification Is Becoming A Core Feature of Crypto Security
Biometric technologies use physical features to enable identity verification, such as voice, fingerprints, or facial features. These methods help keep criminals from stealing data to carry out illicit transactions, which is why crypto exchanges and individual users are increasingly integrating them. Exchanges utilize technologies such as electronic Know Your Customer (eKYC) and liveness detection to create a multilayered security system…….Continue reading…. By Samuel […] -

This is the part of 2FA/TOTP that many people don’t realize:
Your phone isn’t receiving the 6-digit code from the server.
Instead, your authenticator app acts like a specialized cryptographic calculator. 🧮🔐
It takes a shared secret key, combines it with the current time, and applies the TOTP algorithm to generate a temporary 6-digit code.
At the same time, the server independently performs the same calculation using its copy of the secret key and the same time counter.
Same secret + same time counter + same algorithm = same result.
That’s why your authenticator app can generate the correct code without receiving it from the server.
It’s a simple idea, but a brilliant application of cryptography.
You can even test this yourself: add the same TOTP secret to both Google Authenticator and Microsoft Authenticator. Even if you set them up at different times, both apps can independently generate the same 6-digit code at the same time.
And here’s another important point:
The algorithm doesn’t need to be secret.
TOTP is based on publicly known, standardized cryptographic algorithms such as HMAC. What needs to remain secret is the shared secret key.
So:
🧮 Algorithm/math: Can be publicly known.
🔑 Secret key: Must remain private. Never share it.
⏱️ Time: Isn’t secret.
🔐 Security: Comes from protecting the secret key, not from hiding the algorithm.That’s a core principle of modern cryptography: A cryptographic system should remain secure even when the algorithm is publicly known. The secret is the key.

I’m looking for a good alternative to Google Authenticator for Two Factor Authentication.
What authenticator app are you using, and would you recommend it? And why would you recomend it?
I have not experienced any errors and its really working fine. I am just trying to stay away from #Google Services as much as posible

I'm glad @Waterfox Private Search has tweaked their UI to show more results, this makes it much more worthwhile and useful!
Now if they could just stop emailing me a code when I have to log in (which seems very frequent). At least give me the option to use TOTP instead!

Чек‑лист внедрения аутентификации Manticore в продакшн
В проде подход «включил и готово» почти никогда не работает. Для автономного узла техническая последовательность короткая: включить auth , перезапустить Manticore, создать администратора и обновить клиентов. В топологии с распределёнными таблицами или репликационными кластерами нужна дополнительная подготовка, потому что узлам тоже приходится аутентифицироваться друг у друга. Относитесь к внедрению как к небольшому релизу. Сначала инвентаризируйте клиентов и узлы, подготовьте данные аутентификации и отрепетируйте процедуру для своей топологии. Затем переключайтесь. Репетиция выявит сбои до технологического окна. Этот чек‑лист написан для пользователей, которые планируют включить аутентификацию и хотят сделать это максимально безопасно для текущей системы. Помните, что аутентификация отключена, пока вы не настроите auth ; после переключения клиенты, которые по‑прежнему не передают учётные данные будут получать отказ. Выберите процедуру по топологии:

📄 "The (Un)suitability of Passwords and Password Managers in Virtual Reality" by Emiram Kablo, Yorick Last, Patricia Arias Cabarcos, and Melanie Volkamer was accepted for presentation at the #Conference on Sociotechnical #Cybersecurity and #Privacy (SCP 2026). The paper examines the experiences, preferences, and expectations of 126 #VR users regarding #authentication in virtual reality through a user study.
👓 The study revealed a clear preference for simple passwords, as well as interest in #biometric methods and #password managers. It then conducts the first comprehensive evaluation of existing password managers in VR based on 91 cognitive walkthroughs and expert reviews. The results show that while password managers improve #usability, important features such as cross-app #autofill are still missing. Building on this, the paper formulates recommendations for more #secure and user-friendly VR authentication.
🔎 In a Google search for “Password Managers in VR,” the preprint currently ranks first.
SCP will take place September 2nd and 3rd, 2026 in Belval, Luxembourg.

Как защитить Manticore Search с помощью встроенной аутентификации и авторизации
Поиск нередко считают просто инфраструктурой. Но в продакшене он фактически работает как API приложения: принимает пользовательский трафик, отдаёт бизнес‑данные, обслуживает дашборды и нередко стоит рядом с записями, которые не должны быть доступны каждому клиенту в сети. В Manticore Search теперь (с релиза 27.1.5 ) есть встроенная аутентификация и авторизация — для SQL по протоколу MySQL, для HTTP/HTTPS‑эндпоинтов и для операций, связанных с репликацией. Аутентификация отвечает на вопрос «кто делает запрос?». Авторизация — «что этому пользователю разрешено делать?». Пользователи, которые уже используют Manticore могут подключить новую функциональность, сохранив привычные способы работы с Manticore. Существующие SQL и HTTP‑клиенты сохраняют свои обычные паттерны подключения. В приложениях требуются минимальные изменения.

[Перевод] Книга аутентификации
Это моя личная книга по аутентификации. Она представляет собой сборник руководств, рекомендаций и примеров по внедрению аутентификации в веб-приложениях, основанный на моем личном опыте. Книга совершенно бесплатна и не содержит рекламы. Надеюсь, она будет полезна всем, кто хочет узнать больше об аутентификации, безопасности и веб-технологиях в целом. Как следует из названия, эта книга в значительной степени посвящена системе аутентификации и авторизации для веб-приложений. Более общие вопросы безопасности см. в серии “Шпаргалки OWASP” . Если у вас возникнут какие-либо вопросы, не стесняйтесь задавать их на сервере Discord или в обсуждениях на GitHub . Разработано и поддерживается Pilcrow . Исходный код доступен на GitHub .

ADDED ON EDIT: Technically, some of the links DO work. But we have multiple email addresses authorized to use the same AdSense account. You can't just log in with address Alpha to look at an issue reported to address Beta even though you're looking at the same account. That would simply be user-friendly and convenient.
I cannot help but wonder how the people at Google decide to create a template for AdSense notifications. Every link is completely useless. You click on them and you land on the home page of your account.
Site approved? See the home page. If you're lucky, the site is actually named in the email. If not, well, scroll through the list of sites and figure out what changed.
Got a violation notification? Don't worry. We won't tell you which site, which page, or what the specific violation was. But we'll redirect you to a meaningless list of potential policy guidelines without any helpful context.
The only Google service more braindead than the AdSense notifications in my experience is the user verification process, which repeatedly fails you regardless of how many emails you receive or how often you put in the only phone number ever associated with the account.
I only deal with these moronic services because years ago we naively believed that Google actually knew what it was doing, and now our portfolio is stuck in the system.
Happily, we gave up on Google Analytics years ago and now can delete all the oblivious emails they keep sending us even though we're not tracking any sites.

Is there a standard for indicating that a given domain should use #OAuth for logins?
For example, my webapp gets a signup or login attempt from
[email protected]and does a lookup (maybe a #DNS TXT record?) and gets a result which tells me I should / must use OAuth for logins on that domain?If such a standard doesn't exist, should it? Seems to me that it would be every useful.

The change removed the need for clients to pre-discover which region to sign for, improving both latency & regional failover resiliency.
The code change was small - the 6-month rollout wasn't.
