The Keynote will be available to stream on apple.com, the Apple Developer app, the Apple TV app, and the Apple YouTube channel. On-demand playback will be available after the conclusion of the stream.
I have a similar scenario, receiving a notification on my iPhone that approx 80 of my username/passwords are the subject of a data breach. However many of my passwords on this notification are different. Ie, not the same password across all sites. I often use a similar password but with different letters or numbers at the end.
I can understand the concept of, say, a retailers website getting hacked and suffering a data breach that contains a list of all its customers including my email and password. And I get that as a precaution Apple may notify me about a potential breach for any other websites where I may have the same email & password combination. But why would I be notified of many other passwords being at risk? Is it because they may contain 'part' of the same password? But that still doesn't explain the notifications relating to my wife and sons passwords which are nothing like mine.
i bought an iphone 8 plus on ebay and right when i was signing in to all my accounts that i used before it always says its been in a data leak, i want to know if this is from me buying an iphone from ebay or if its just like those scam phone calls you get when they ask for your credit card information.
Clearly 1 causes me great concern but 2 would seem reasonable, in that there will be numerous people worldwide that would randomly choose the same 5 figure number, of which some poor sole has had their data breached.
Re-use a password, and some miscreant will now have access to that service, and whatever additional access can be gained from there. Access ro an Apple,ID (and particularly one without two-factor enabled) is a Bad Day for the account holder, too.
But to keep passwords for every websites is insane. How can we remember those passwords? If this is the solution then it sucks. Normal people can't remember each and every password (now you will tell that you don't have to remember the password but instead your phone or computer will do it. Unfortunately, Life is not that simple.
All of these work the same way. They store your passwords using strong encryption, and you only have to remember one password for the app itself to find any password and have it entered automatically into the website or app.
haveibeenpwned contacts multiple famous services such as wattpad and mathway, etc to see if they have been exposed to hackers and accounts have been sold or leaked, and might also confirm that your email or phone-number is part of that list.
Contrastingly Apple's Keychain services use a different method. Like many VPN services like NordVPN, Keychain actually references many deep web links to compromised accounts and immediately contacts the owner. Quote:
OTP security tokens are microprocessor-based smart cards or pocket-size key fobs that produce a numeric or alphanumeric code to authenticate access to the system or transaction. This secret code changes every 30 or 60 seconds, depending on how the token is configured.
OTP security tokens can be implemented using hardware, software or on demand. Unlike traditional passwords that remain static or expire every 30 to 60 days, the one-time password is used for one transaction or login session.
When an unauthenticated user attempts to access a system or perform a transaction on a device, an authentication manager on the network server generates a number or shared secret, using one-time password algorithms. The same number and algorithm are used by the security token on the smart card or device to match and validate the one-time password and user.
Many companies use Short Message Service (SMS) to provide a temporary passcode via text for a second authentication factor. The temporary passcode is obtained out of band through cellphone communications after the user enters his username and password on networked information systems and transaction-oriented web applications.
The OTP values have minute or second timestamps for greater security. The one-time password can be delivered to a user through several channels, including an SMS-based text message, an email or a dedicated application on the endpoint.
The U.S. National Institute of Standards and Technology (NIST) considered deprecating SMS for 2FA and one-time passwords in 2016. Ultimately, however, the organization decided that while using SMS as a second authentication factor is not the most secure option, it is more effective than single-factor authentication.
Experts such as those at NIST recommend enterprises consider one-time password delivery methods besides SMS -- and avoid delivering OTPs via SMS to email addresses or VoIP numbers, which cannot prove device possession.
The one-time password avoids some common pitfalls of password security. With OTPs, IT administrators and security managers do not have to worry about composition rules, known-bad and weak passwords, sharing of credentials or reuse of the same password on multiple accounts and systems.
Another advantage of one-time passwords is that they become invalid in minutes -- in the case of TOTPs -- or once they have been used -- in the case of HOTPs. In this way, one-time passwords prevent attackers from obtaining the secret codes and reusing them.

During the account setup phase when installing ArcGIS Enterprise software components (ArcGIS Server, Portal for ArcGIS or ArcGIS Data Store) on Windows operating systems, when prompted to specify the account name and password, the following error is returned after specifying a password:
Cause This issue occurs due to the 'Password must meet complexity requirements' policy setting defined by Windows. The policy setting is enabled by default, and this causes the installer to return the error if the user-defined password does not meet the minimum complexity requirements. For a comprehensive list of the minimum password requirements, refer to Microsoft: Password must meet complexity requirements.
If adhering to the password complexity requirements is not an option, prior to executing the ArcGIS Enterprise installer, disable the 'Password must meet complexity requirements' policy setting via the Windows Local Security Policy console using the following instructions:
In cryptography, key stretching techniques are used to make a possibly weak key, typically a password or passphrase, more secure against a brute-force attack by increasing the resources (time and possibly space) it takes to test each possible key. Passwords or passphrases created by humans are often short or predictable enough to allow password cracking, and key stretching is intended to make such attacks more difficult by complicating a basic step of trying a single password candidate. Key stretching also improves security in some real-world applications where the key length has been constrained, by mimicking a longer key length from the perspective of a brute-force attacker.[1]
Key stretching algorithms depend on an algorithm which receives an input key and then expends considerable effort to generate a stretched cipher (called an enhanced key[citation needed]) mimicking randomness and longer key length. The algorithm must have no known shortcut, so the most efficient way to relate the input and cipher is to repeat the key stretching algorithm itself. This compels brute-force attackers to expend the same effort for each attempt. If this added effort compares to a brute-force key search of all keys with a certain key length, then the input key may be described as stretched by that same length.[1]
If the attacker uses the same class of hardware as the user, each guess will take the similar amount of time to process as it took the user (for example, one second). Even if the attacker has much greater computing resources than the user, the key stretching will still slow the attacker down while not seriously affecting the usability of the system for any legitimate user. This is because the user's computer only has to compute the stretching function once upon the user entering their password, whereas the attacker must compute it for every guess in the attack.
This process does not alter the original key-space entropy. The key stretching algorithm is deterministic, allowing a weak input to always generate the same enhanced key, but therefore limiting the enhanced key to no more possible combinations than the input key space. Consequently, this attack remains vulnerable if unprotected against certain time-memory tradeoffs such as developing rainbow tables to target multiple instances of the enhanced key space in parallel (effectively a shortcut to repeating the algorithm). For this reason, key stretching is often combined with salting.[1]
