What you need to know
A bug in Chrome version 127 caused passwords to vanish for around 15 million Windows users. The issue lasted for nearly 18 hours before being fixed.
Users had to use a command line flag as a temporary fix, but the final solution required just a browser restart (yes, turn it off and on again!).
This incident highlights the risks of relying solely on browser-based password managers.
To put it bluntly, it's not been a great month for tech giants. Earlier this month, the CrowdStrike bug brought many businesses to a complete standstill and left millions facing the Blue Screen of Death, causing disruption many are still recovering from following postponed flights and surgeries, to name just a few inconveniences.

Well, not to be left out, Google had to cause its own chaos, according to this report from Forbes. Windows users clearly haven't suffered enough and an estimated 15 million of them were locked out of their own passwords for nearly 18 hours from July 24 to July 25 due to "a change in product behavior" with Google Chrome.
