Documented steps
Log in to a registry: `podman login [options] [registry]` — with no registry it uses the first search registry from registries.conf.
Supply credentials interactively, or non-interactively: `podman login -u user -p pass registry.example.com` (avoid -p on the command line in shared shells).
Read the password from stdin instead: `echo $TOKEN | podman login -u user --password-stdin quay.io` — safe for CI/secrets.
Supply it as a podman secret: `echo -n $TOKEN | podman secret create regtoken -` then `podman login --secret regtoken -u user quay.io`.
Store creds in a persistent authfile so they survive reboot: `podman login --authfile ~/.config/containers/auth.json quay.io`.
Verify the logged-in user: `podman login --get-login quay.io`; log out with `podman logout`.

Known gotchas
The DEFAULT authfile is ${XDG_RUNTIME_DIR}/containers/auth.json, which lives under /run and is EPHEMERAL — creds do NOT persist across reboot unless you pass --authfile to a persistent path.
There is a fallback to $HOME/.docker/config.json only if the first location is invalid, and creds are stored base64-encoded.
Override the authfile path globally with the REGISTRY_AUTH_FILE env var.
--tls-verify defaults to true; skipped only for registries marked insecure in containers-registries.conf.
--cert-dir (custom registry certs) is not available on remote podman clients.
If no username is passed, podman reuses existing stored credentials.
