Unable to Log in to Salesforce Due to Security Verification Issue – Password Reset Also Not Working

Hi @jyoti kumari,  

If you're being prompted for a security verification code and no longer have access to the registered email address or phone number, the password reset process may not resolve the issue on its own. Try using a different browser, clearing cache/cookies, or opening an incognito/private browsing window before attempting the login again.

If the issue persists, you'll likely need to contact your Salesforce administrator so they can verify your identity and help reset your access. If this is a personal Developer Edition or Trailhead account, reaching out to Salesforce Support may be the best next step.
