The reason may be that the account password was entered incorrectly. The user name of a Google account is represented by an email address. Users can get a Google account by signing up for Gmail, or they can apply by using existing email.

Vulnerabilities in GooglePlay App Store:

Due to lax censorship, malware in GooglePlay App Store has been frequently exposed. The problem is very serious. Some researchers have found that the application in GooglePlay Store can reveal the developer's private key.

JasonNieh, a professor of computer science at Columbia University, and NicholasViennot, a doctoral student, found that using PlayDrone tool software can crack and bypass GooglePlay's security system to download GooglePlay applications, and recover and analyze the source codes of these applications. They used multiple servers to crack and have successfully cracked 880,000 free applications.

Its GooglePlay store has also been criticized. A risky application is downloaded millions of times a month in its store, and even malicious applications disguised as Google Store are available for users to download in GooglePlay.
