How to Read & Inspect Login Tokens (JWT) Without Leaking Your Password
See who you are logged in as and when your session expires in 2 seconds.
In Simple Words (Analogy)
Think of a JWT like a VIP festival wristband. When you log in with your password, the website gives you this wristband. As you browse, your browser shows the wristband to open doors instead of asking for your password every second.
When Do You Need This? (Real-Life Situations)
- Your app suddenly logs you out or shows '401 Unauthorized' and you want to know why.
- You want to check the exact second your session expires ('exp' date).
- You want to see what permissions or user roles ('admin', 'editor') your account has.
- You are a developer testing authentication between your frontend and backend.
How to Use It in Devstation (Step-by-Step)
1Copy your JWT token string (usually starts with 'eyJ...').
2Paste it into devstation's JWT Inspector & Decoder.
3Instantly read the decoded user details, issued date, and human-readable expiration time.
Prefer The Command Line? Linux / Bash Way
$ echo "$TOKEN" | cut -d. -f2 | base64 --decode 2>/dev/null | jq .Splits the second part of the token, decodes base64 bytes, and prints clean JSON in your terminal.
Why This Benefits & Protects You
Many public token websites send your secret keys to their servers, exposing your login credentials. devstation decodes tokens strictly inside your browser memory—no data is ever sent across the internet.
