By default, Phoenix creates an admin user with the email admin@localhost and the password set by the PHOENIX_DEFAULT_ADMIN_INITIAL_PASSWORD environment variable. If you used the Helm chart, the command you ran should give you the correct initial password. However, if authentication is enabled but the password does not work, ensure you are using admin@localhost as the username (not just "admin") and the decoded password as retrieved from the secret. Also, note that some deployments may force a password reset on first login, so check for any reset prompts in the UI after your first attempt.If you still cannot log in, verify that the PHOENIX_DEFAULT_ADMIN_INITIAL_PASSWORD was set correctly at deployment time and that the secret was not overwritten or changed after the pod started. If issues persist, you may need to reset the admin password or redeploy with a new secret. For more details, see the Phoenix authentication documentation and Helm chart notes.Would you like a step-by-step troubleshooting guide?Sources: - Phoenix authentication documentation - Helm chart NOTES.txt - GitHub issue: admin password env var
