iMac password reset itself after upgrading to Sequoia 15.3

iMac 27", 2019. Recently upgraded to Sequoia 15.3. This morning, my password is no longer recognized as correct. Fortunately, was able to unlock with Apple Watch, but can't reset iMac password without first entering old password, which is being rejected. Likely will request password when trying login with watch soon, so I need to resolve issue quickly. Thanks!

Mac OS does not have the ability to change its own password so there is some other explanation. However please follow the steps in:


If you forgot your Mac login password


and if necessary:


If you forgot your Apple ID password
