HELP! Locked out of iCloud Email by Third Party
How can I reclaim my email account? I use my iCloud email through Blue Mail on my Samsung S10.
I woke up on Saturday morning to a heap of authentication code text messages on my phone. I thought that was strange. I realised on Sunday that I hadn't received any emails and saw that my iCloud email had been unsynchronised. I looked through the setting and realised that my password which is usually 8 digits long is now 20 digits long. It wasn't accepting my password, so I logged into iCloud on my desktop and changed my password hoping that might fix the issue. It hasn't. I keep getting an alert that says "Sync Failed, your username and password may be incorrect (3010) Email server returned: NO,{AuthenticationFailed},
How can I fix this issue?
