Keychain displays dots instead of password.
I ran into an issue with a particular website that somehow appears to corrupt the password that gets saved in Keychain.
Using an Apple Mac Book Pro (late 2013) with osSierra 10.12, I saved my login credentials on the website and when I logout and try to log back in it fails. I checked the password in Keychain and all it shows are dots. When I view the account info in Safari, it too shows only dots and not the password, and finally on my iPhone 6s Plus with iOS 10.0.2 it shows dots as well. I've spoken with Apple tech support and because it's only happening with battle.net and not any other sites they've asked me to reach out to you. If I manually type the password in I login successfully.
Things I've done for troubleshooting. Deleted account info from Safari and verified info is gone from iPhone and Keychain. Saved credentials during login, logged out and attempted login and using saved credentials it failed.
In iCloud settings I deselected Safari, removed account info from Safari and verified it was deleted from Keychain as well. Saved credentials as I logged back into website, logged out and attempted to login with newly saved credentials and it failed again, so this eliminated the possibility of the iCloud Keychain causing the corruption.
Thank you.
