Steam 强制重置密码还是我账号被盗了？你的账号有没有异常？

如题。
目前在用两个steam账号，结果两个号密码都被重置了。
第一个是昨天，第二个是今天。
开始我怀疑是自己电脑上被人动了手脚，排查一圈也没发现什么异常。
因为昨天那个账号对我来说没什么用，是打算做一个steambot用的账号，我也就没多想。
今天我常用的账号刚才突然登不上去了，去邮箱看了下提示密码被修改。
两个账号一个是QQ邮箱，一个是gmail，并不存在email同时被盗的可能性。
gmail我一个月都不登陆一次的。

而且看到一封邮件：

Dear Steam User,

On July 25th we learned of a Steam bug that could have impacted the password reset process on your Steam account during the period July 21-July 25. The bug has now been fixed.

To protect users, we are resetting passwords on accounts that changed passwords during that period using the account recovery wizard. You will receive an email with your new password. Once that email is received, it is recommended that you login to your account via the Steam client and set a new password.

Please note that while your password was potentially modified during this period the password itself was not revealed. Also, if you had Steam Guard enabled, your account was protected from unauthorized logins even if your password was modified.

We apologize for any inconvenience.
