Is it okay to store access token in local storage?

On the downside, localStorage is potentially vulnerable to cross-site scripting (XSS) attacks. If an attacker can inject malicious JavaScript into a webpage, they can steal an access token in localStorage. Also, unlike cookies, localStorage doesn't provide secure attributes that you can set to block attacks.

Where should I store my access token?

The usual practice is to store access tokens in the browser's session storage or local storage. This is because we need to persist access tokens across page reloads, to prevent the need to re-authenticate on every reload. This provides a better user experience.

Is storing JWT in local storage secure?

A JWT needs to be stored in a safe place inside the user's browser. Any way,you shouldn't store a JWT in local storage (or session storage). If you store it in a LocalStorage/SessionStorage then it can be easily grabbed by an XSS attack.

Should I store access token in database?

Some access tokens last an hour or two, and are well suited for storing in the session. Others are long-term tokens, for example facebook provides a 60-day token, and these make more sense to store in a database. Either way, storing the token will free us from having to ask the user to authorize again.

What should you not store in local storage?

Given the potential vectors where malicious actors can access information on your browser's local storage, it is easy to see why sensitive information such as Personally Identifiable Information (PII), authentication tokens, user locations and API keys, etc., should never be stored in the local storage.

Is local storage more secure than cookies?

Although cookies still have some vulnerabilities, it's preferable compared to localStorage whenever possible. Why? Both localStorage and cookies are vulnerable to XSS attacks, but it's harder for the attacker to do the attack when you're using httpOnly cookies.

Can access token be stolen?

While these tokens are useful for enabling key IT services, they're also vulnerable to theft.

What is the best place to store JWT?

JWT should be stored in cookies. You can use httponly and secure flags depending on your requirements. To protect from CSRF samesite cookie attribute can be set to strict if it generally fits your application - it will prevent logged-in users of your site to follow any link to your site from any other site.

Is local storage vulnerable to XSS?

XSS attacks inject malicious scripts into web applications, and unfortunately, both LocalStorage and SessionStorage are vulnerable to XSS attacks. XSS attacks can be used to get data from storage objects and add malicious scripts to the data stored.

Is local storage vulnerable to CSRF?

Both localStorage and cookies are vulnerable to XSS attacks, but it's harder for the attacker to do the attack when you're using httpOnly cookies. Cookies are vulnerable to CSRF attacks, but it can be mitigated using sameSite flag and anti-CSRF tokens.

Where should I store access token and refresh token?

If your application uses refresh token rotation, it can now store it in local storage or browser memory. You can use a service like Auth0 that supports token rotation.

Where do you keep the access token frontend?

Where should I store my tokens in the front-end? There are two common ways to store your tokens. The first is in localStorage and the second is in cookies. There is a lot of debate over which one is better with most people leaning toward cookies as they are more secure.

Is it safe to store refresh token in database?

Do not store or use OAuth access tokens or refresh tokens on web or mobile clients. OAuth access tokens and refresh tokens should be encrypted and stored in a secure database. Your application should use a strong encryption standard such as AES.

How long should access tokens last?

By default, access tokens are valid for 60 days and programmatic refresh tokens are valid for a year. The member must reauthorize your application when refresh tokens expire.

Should you cache access tokens?

Cache tokens

Because fetching new tokens is expensive, we recommend using a token cache to prevent unnecessary requests. After retrieving a token, store it in an in-memory cache, like Memcached, or a built-in ASP.NET cache service.
