Is It Safe To Store Access Token In Local Storage
Is It Safe To Store Access Token In Local Storage. That makes it generally safe to store locally, since you'd have to refresh or reauthenticate (or just reissue, in the case of an anonymous token*) after the expiry in any case. While i feel like i made myself clear that you should never ever store sensitive information in local storage in the previous section, i feel the need to specifically call out json web tokens (jwts).
Generated token doesn't contain part or the whole the credentials (user or password. I did quite a bit of research on this a while ago and came to the conclusion that local storage is better than cookies for storing any type of authentication token (or at least, just as secure). A jwt needs to be stored in a safe place inside the user's browser.
So To Err On The Side Of Caution And Dramatically Reduce Your Risk For A Security Incident:
Generated token doesn't contain part or the whole the credentials (user or password. Storing a token in localstorage is insecure. Browser local storage and session storage can be readfrom javascript, and as such are not secure to store sensitive information such as tokens.
Prone To Csrf But Can Be Mitigated, A Bit Better In Terms Of Exposure To Xss.
It is perfectly safe to use localstorage or sessionstorage to store client tokens to perform subsequent authenticated requests to your api, this, as long as you have taken good meassures in your api in place to manage that token and keep it safe: If there is xss in the application, the access token will be stolen. While i feel like i made myself clear that you should never ever store sensitive information in local storage in the previous section, i feel the need to specifically call out json web tokens (jwts).
For That I Have Implemented Token Authentication And Therefore Decided To Store The Token In Local Storage Using Redux Persist.
[signature] now, let’s explore which is the best way to store a jwt token. However, as far as i can gather, the attack vector here are browser plugins. Regardless, when using localstorage, one does not need to think about this attack vector.

Store tokens in a secure storage that the os offers and limit access to that storage. I'm not sure what you plan to do with this data (warn the user when their session is running out? For example, leverage keystore for android and keychain for ios.
If You Store It Inside Localstorage, It's Accessible By Any Script Inside Your Page (Which Is As Bad As It Sounds, As An Xss Attack Can Let An External Attacker Get Access To The Token).
The token is not just. It’s getting more and more common to use token based authentication, specially on single page applications (spa) that need to communicate with an api. Don’t store json web tokens in local storage.
