Well, in answer to your direct question no, you can't actually change your ID. **You can change your password but not your ID, not without creating a new Apple ID which would mean losing all your iCloud data, purchased apps, music, ect ect.

Data Breach on 6-20-25
"As of June 20, 2025, a massive data breach was reported, exposing over 184 million unique account credentials across major platforms such as Google, Microsoft, Apple, Facebook, Instagram, and Snapchat, among others. This breach involved a database containing usernames, passwords, emails, and URLs for a wide range of applications and websites, including financial accounts, health platforms, and government portals.9
Details of the Breach
- Scope: The breach includes over 184 million unique usernames and passwords, with the data reportedly sourced from infostealer malware that harvested sensitive information from infected devices.9
- Exposed Data: Credentials for Google, Microsoft, Apple, Facebook, Instagram, Snapchat, and other platforms were exposed, including emails, usernames, passwords, and URLs. Additionally, financial and health-related data were also compromised.9
- Discovery: Cybersecurity researcher Jeremiah Fowler discovered the database, which was found online without encryption or password protection. Fowler verified the accuracy of the data by contacting individuals listed in the dump, many of whom confirmed the credentials were correct.9
- Response: After Fowler reported the issue, the hosting provider took the database offline. However, the source of the breach and the owner of the data remain unknown.9
- Platform Responses: Snapchat stated that it found no signs of a breach on its own systems. However, the potential exposure of credentials raises concerns about downstream impacts on user accounts.9
Recommendations
- Password Changes: Users are advised to change their passwords regularly, especially for critical accounts such as email, banking, and social media.9
- Multi-Factor Authentication (MFA): Enabling MFA, particularly using more secure methods like authenticator apps or hardware keys, is strongly recommended, as SMS-based MFA is increasingly seen as insecure.9
- Data Hygiene: Experts emphasize the importance of practicing good internet hygiene, including avoiding the storage of sensitive information in unencrypted formats and using secure password managers.9
This breach comes shortly after another massive data leak involving 16 billion records, though this latest incident focuses on previously unreported credentials.3"
AI-generated answer. Please verify critical facts.
Personally I use MFA for all my critical accounts and Passkeys for Google, Microsoft, Apple, Facebook ect, in fact any site that will accept Passkeys currently.
However as the above search result suggests, "Users are advised to change their passwords regularly, especially for critical accounts such as email, banking, and social media."
So, for peace of mind it's easy enough these days to use Apple Passwords (if you use that) or other Password Managers to change your passwords for those critical accounts. **I wouldn't rush into it though if you have 2FA enabled for eg. your Apple account because every login must be verified by a "trusted" device and you would be notified if there were any other attempts. The same applies to Google Microsoft and Facebook. You will get a "Was this you?" notification by email and a suggestion to change your password if it wasn't. DO NOT follow links from these emails but go to the sites themselves and change your password.
) you can be easily confused.
