API key management: How to manage developer credentials and API keys securely

Software teams are in charge of many secrets that keep their businesses running. Some are obvious, like database passwords and SSH keys. But others are easy to forget, like API tokens created for a quick integration, webhook secrets copied into setup notes, or environment variables added during late deployments. These credentials often work invisibly. They connect tools, manage data, trigger workflows, and keep applications talking to each other without additional logins. This convenience is exactly why they need tighter control. If one of those secrets leaks, such as an API key, an attacker won’t need to impersonate an employee or get past a multi-factor authentication (MFA) prompt. The system may simply accept a leaked key as valid access. For many SMBs, API key management only becomes a priority after something has already gone wrong. For example, if a repository is exposed, or a staging key also works in production. Developer credential management is the process of bringing those secrets out of informal habits and siloed repositories into a controlled system. API keys, database passwords, SSH keys, deployment tokens, and service account credentials should be treated as privileged business access: they need clear ownership, secure storage, limited permissions, and a plan…
