GitHub and GitLab both support WebAuthn/FIDO2 hardware keys for phishing-resistant 2FA — far stronger than SMS or TOTP. Here are the best MFA and credential tools to lock down your developer accounts.
If you're a developer, your GitHub or GitLab account is the keys to the kingdom. Source code, CI/CD pipelines, deploy tokens, package registries — all behind a single login. And yet, a huge number of developers still protect that login with SMS-based 2FA or a TOTP app like Google Authenticator. Both can be phished.
That's the core problem. SMS codes can be intercepted via SIM-swap attacks. TOTP codes can be stolen by a convincing phishing page that relays them in real time. Neither is bad — they're better than nothing — but they share a fundamental weakness: a human types the code into a form, and that form might not be the real one.
WebAuthn/FIDO2 hardware security keys solve this. The key cryptographically authenticates to the actual domain (e.g. github.com), and the browser verifies the origin. A phishing page at github.security-login.com gets a different origin, so the key simply refuses to respond. No code to type, nothing to intercept. This is called phishing resistance, and it's the single biggest upgrade you can make to your account security.12
Both platforms support WebAuthn-compatible security keys as a 2FA method:
The hardware keys that work here include the YubiKey 5 Series (USB-C, USB-A, and NFC variants, supporting FIDO2/WebAuthn, U2F, and OpenPGP)4, Nitrokey (open-source FIDO2 keys)5, and SoloKeys (open-source FIDO2-only keys)6. Any of these will work with GitHub and GitLab's WebAuthn flows.
Here's where I need to be straight with you: the products in our database aren't dedicated hardware security keys like a YubiKey or Nitrokey. Those are the actual gold standard for this use case, and if you're an individual developer, you should go buy one — a YubiKey 5 NFC runs around $45–55 and covers USB-C, USB-A, and NFC in one device.4
What we do have are enterprise MFA platforms and credential managers that complement or enforce hardware-key-backed authentication at the organizational level. If you're a team lead or security admin trying to lock down your org's GitHub/GitLab access, these are the tools that help you enforce the policy — and they pair well with physical keys.

HID Global is an enterprise identity company that builds physical smart cards, readers, and digital MFA into a single platform. If your organization already uses HID smart badges for building access, extending that to GitHub/GitLab login is the most natural path. It's the closest product in our database to a true hardware-key workflow because the physical credential is the foundation — not an afterthought.
For dev teams, this means you can enforce possession-based authentication (the employee must have the physical card or token) alongside a PIN or biometric, which mirrors the FIDO2 model. It's overkill for a solo developer, but for an enterprise that wants one identity system across physical and digital access, HID is the strongest pick.
Okta is the 800-pound gorilla of workforce identity. Its adaptive MFA engine evaluates context — device, location, network, time — and can step up to a hardware key or push notification when risk is high. For organizations using Okta as their SSO provider, routing GitHub and GitLab through Okta means you can enforce hardware-key-backed login without each developer configuring keys individually on each platform.
The advantage here is policy centralization. You set the rule once in Okta ("GitHub login requires a FIDO2 key"), and it applies to everyone. The downside is cost and complexity — Okta is an enterprise platform, not a quick setup for a five-person team.
LoginTC is a RADIUS-based MFA solution that integrates with VPNs, firewalls, and legacy systems. Its most relevant use case for this guide is self-hosted GitLab behind a VPN: if your GitLab instance isn't on the public internet and developers connect through a VPN gateway, LoginTC can enforce MFA at the VPN layer before anyone even reaches GitLab's login page.
It's a niche fit — most teams use GitHub.com or GitLab.com SaaS — but if you're running self-hosted infrastructure, LoginTC fills the gap between "VPN-only access" and "full identity provider."
Keeper is a credential vault that stores passwords, API keys, and Git tokens with zero-knowledge encryption. It pairs with hardware keys by requiring a FIDO2 token for vault unlock — so even if someone steals your laptop, they can't access your stored GitHub tokens without the physical key.
For developer teams, Keeper's shared folders let you distribute deploy keys and CI secrets without pasting them into Slack or a wiki. It's not a replacement for a security key on your GitHub account; it's a complement that manages the other secrets your team handles.
1Password Business is a password manager with Watchtower, which alerts you when stored credentials appear in known data breaches. Like Keeper, it supports hardware-key integration for vault unlock and can store Git tokens and SSH keys in its secure notes and SSH item types.
The differentiator from Keeper is Watchtower's breach monitoring — if a developer's password shows up in a breach dump, you get an alert. For teams that want credential management and proactive breach detection, 1Password is the stronger choice. For pure secrets vaulting with more granular sharing controls, Keeper edges ahead.
If you're an individual developer, the path is simple:
If you're managing a team, the path is:
The best security key for GitHub and GitLab is a YubiKey 5 Series — it's the most widely compatible, well-supported FIDO2 key, and both platforms explicitly support it.34 If you want open-source alternatives, Nitrokey and SoloKeys are solid choices with the same WebAuthn protocol support.56
Among the enterprise tools in our database, HID Global MFA is the closest to a hardware-key workflow, Okta is the best for centralized policy enforcement, and Keeper and 1Password are the best complements for managing the secrets your keys protect. None of these replace a physical key — they make keys manageable at scale.
