Resets admin@bitween.systems to the default password (case-insensitive lookup, normalized lowercase email) every boot, since the EF HasData seed only ever applies once per database.

🛠 Guidelines to remediate hardcoded secrets
- Understand the implications of revoking this secret by investigating where it is used in your code.
- Replace and store your secret safely. Learn here the best practices.
- Revoke and rotate this secret.
- If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.
To avoid such incidents in the future consider
- following these best practices for managing and storing secrets including API keys and other credentials
- install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
🦉 GitGuardian detects secrets in your source code to help developers and security teams secure the modern development process. You are seeing this because you or someone else with access to this repository has authorized GitGuardian to scan your pull request.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to This change creates or resets a designated administrator account on every startup using a password embedded in the application, may re-enable password login, and may not correctly grant administrator access to newly created accounts. It can expose deployments through a predictable privileged credential, undo password rotation, or prevent startup, so the PR is not merge-ready until these behaviors are made safe.

Move DefaultAdminPassword out of source code.
SecurePasswordHasher.Hash protects storage, but it does not protect the plaintext credential embedded in source. Load a one-time bootstrap secret from deployment secret storage and require explicit rotation.

Handle the unique-key race during admin seeding.
Concurrent instances can both read no account before Add. The existing unique Accounts.Email index prevents duplicate rows, but one SaveChanges call can fail with a unique-key exception. Catch that exception and reload the account, or use an atomic upsert. Add a concurrent-startup test.

Validate the account role before changing credentials.
If admin@bitween.systems belongs to a non-admin account, the email-only lookup reuses that account without assigning AccountRole.Admin, then AddEmailLoginMethod unconditionally replaces its password. Handle this email/role collision through a controlled bootstrap path before changing credentials.

Do not overwrite an existing administrator password on every startup.
EnsureDefaultAdmin always calls Account.AddEmailLoginMethod for the existing account. The method directly assigns the supplied hash to Password. This restores the default credential after every restart and defeats password rotation and revocation. Set the password only during initial provisioning or an explicit reset.
