When should I create refresh token?
Explanation. Refresh tokens are random strings generated by the authentication server. They are generated after successful authentication (for example, if the username and password of the user are valid). Their sole purpose is to remove the need to exchange user credentials repeatedly.
Where do I put the refresh token?
Access token and refresh token shouldn’t be stored in the local/session storage, because they are not a place for any sensitive data. Hence I would store the access token in a httpOnly cookie (even though there is CSRF) and I need it for most of my requests to the Resource Server anyway.
Do refresh tokens expire?
Refresh tokens can expire, although their expiration time is usually much longer than access tokens. If your refresh token is invalid and also don’t have a valid access token for a user, you must send them through an OAuth authorization flow again.

How do I find my browser token?
Token expiration is handled automatically by the cache. You can see the current state of the token cache on chrome://identity-internals . There are some cases, such as when the user changes their password, when non-expired access tokens will stop working.
What is a token for login?
An access token is an object encapsulating the security identity of a process or thread. An access token is generated by the logon service when a user logs on to the system and the credentials provided by the user are authenticated against the authentication database.
How can I get JWT token password?

What is salt in JWT?
Salting the HASH
The most used technique it’s also the simplest: we just concatenate a string, called salt, that in our case is a secret password. So the previous example would be something like this: let token = { data, hash: SHA256(JSON.
Should salt be stored in database?
Now, since the goal of the salt is only to prevent pre-generated databases from being created, it doesn’t need to be encrypted or obscured in the database. You can store it in plaintext.
Is JWT the same as OAuth?

How do I make my JWT token more secure?
Once you know you have a secure channel between the server and client you can securely exchange JWT or whatever else you want. This keeps thing simple. A simple implementation makes adoption easier but it also lets each layer do what it does best (let HTTPS handle encryption). JWT isn’t meant to store sensitive data.
What if JWT token is stolen?
If a JWT is stolen, then the thief can can keep using the JWT. An API that accepts JWTs does an independent verification without depending on the JWT source so the API server has no way of knowing if this was a stolen token! This is why JWTs have an expiry value. And these values are kept short.
Is JWT token safe?
Local storage is not as secure as using cookies (reference) but cookies can be subject to CSRF or XSRF exploits. This answer used to say JWT was safer than cookies, because cookies were subject to CSRF attacks. But storing JWT in local storage is not safe either.
