Microsoft app to delete all passwords forever - how to avoid losing yours
A Microsoft app that is used for two-factor authentication will be removing all saved passwords with users urged to act now. Microsoft Authenticator can also used for authentication using face ID to log into things like emails. The app has stored passwords for users, making logging into their accounts easier without the stress of having to remember what their login details are. However, now it's up to them to save their passwords as the app retires the password saving function, reports the Metro. The newspaper reports that Microsoft announced 'the password era is ending' ahead of the change. Microsoft won't remove password support from all of its services, for now, it's just the Authenticator app. Password data on the app will be deleted in August 2025 so it's worth saving your passwords elsewhere before the cut off. The Microsoft Edge browser can be used to save your passwords or you can head to Chrome, Safari and other browsers to do this. You will need to export your passwords from Microsoft Authenticator to be able to save them elsewhere. Microsoft Authenticator is ENDING Autofill Support! ❌ If you choose Microsoft Edge to save your passwords, download its app and change your Settings so it becomes your new password manager. For more information on exporting passwords to somewhere other than Edge, you can visit the Microsoft website. Microsoft warned that if you choose to do this, your passwords will not be encrypted, so you'll need to delete the file when you have transferred your passwords elsewhere. Recommended reading: Virgin Media O2's new warning as switch off could leave users without internet Easy phone mistakes on holiday could cost you hundreds Martin Lewis shares key advice for mobile phone users Microsoft said the change comes as a result of password attacks with its solution being passkeys instead. According to the Metro, Microsoft said passkeys "offer an improved user experience by letting you sign in faster with your face, fingerprint, or PIN, but they also aren't susceptible to the same kinds of attacks as passwords". Remember to move your passwords before August 2025 to avoid them being deleted forever.

Microsoft Confirms Windows 11 Update Causes Security Firewall Error
Windows 11 uodate causes Firewall error messages, Microsoft has confirmed. Microsoft Windows updates: you can't live without them, but living with them can be tough at times. When high-severity vulnerabilities are uncovered, such as CVE-2025-33073, which can lead to Windows system takeover, updating is a security no-brainer. When vulnerabilities are of the zero-day variety and already subject to ongoing attacks, the need to update is even more critical. The problem that Microsoft has, however, is a history of fumbled update issues that have led to mass confusion at best, and at worst, problems like the startup loop of death that prevent users from being able to use their Windows machines. So, when yet another Windows update problem emerges, the user base heaves yet another sigh of exasperation. Here's what you need to know about the Windows 11 firewall configuration error, erm, error. Microsoft Windows Non-Security Update Leads To Misguided Security Concerns Windows 11 users are experiencing issues with a Firewall configuration error when using Windows Firewall with Advanced Security, following the June 26 KB5060829 Windows update. One simply cannot ignore the irony of a non-security update leading to security concerns. Microsoft has now confirmed that the issue is displayed within the Event Viewer under event 2024 for Windows Firewall With Advanced Security. The error appears, Microsoft said, 'as Config Read Failed with a message of More data is available.' This error is triggered every time the Windows device is restarted, Microsoft admitted. The good news in this mess of Microsoft's own making, is that the error 'can be safely ignored,' according to the Seattle tech behemoth. As it does 'not reflect an issue with Windows Firewall.' The Truth Behind Microsoft's Latest Windows Update Fumble So, what is actually going on, beyond the obvious update faux pas? Microsoft's July 2 update, erm, update, explains this error as being 'related to a feature that is currently under development and not fully implemented.' Oh well, that's OK then, and doesn't display any lack of proper validation of update integrity before release at all. I mean, it's good to know that the issue does not have any impact on or to Windows processes and that, as Microsoft has said, it is 'working on a resolution and will provide an update in an upcoming release,' but wouldn't it be better if these things were discovered before the update is made available to one and all? I have approached Microsoft for a statement.
