If you want to remove Google Password Manager from your phone, you can follow these steps:
Open the Google Chrome app on your phone.
Tap the three-dot menu icon in the top-right corner of the screen.
Select “Settings” from the menu that appears.
Scroll down and tap “Passwords.”
Tap the three-dot menu icon in the top-right corner of the screen.
Select “Settings” from the menu that appears.
Tap “Autofill and payments.”
Toggle off the “Autofill forms” option.
You can also choose to turn off “Save passwords” and “Offer to save passwords” to disable password saving in Google Chrome altogether.
Keep in mind that disabling password saving in Google Chrome will also disable autofill and payment information saving for your Google account across all devices where you use Chrome, and it will not delete any passwords that are already saved in your account. If you want to delete your saved passwords from your Google account completely, you can do so by going to the Google Password Manager website on a computer, signing in to your account, and deleting each password entry manually.
