Simple JWT provides two different token types that can be used to prove
authentication. In a token’s payload, its type can be identified by the value
of its token type claim, which is “token_type” by default. This may have a
value of “access”, “sliding”, or “refresh” however refresh tokens are not
considered valid for authentication at this time. The claim name used to store
the type can be customized by changing the
By default, Simple JWT expects an “access” token to prove authentication. The
allowed auth token types are determined by the value of the
AUTH_TOKEN_CLASSES setting. This setting contains a list of dot paths to
token classes. It includes the
'rest_framework_simplejwt.tokens.AccessToken' dot path by default but may
also include the
'rest_framework_simplejwt.tokens.SlidingToken' dot path.
Either or both of those dot paths may be present in the list of auth token
classes. If they are both present, then both of those token types may be used
to prove authentication.
Sliding tokens offer a more convenient experience to users of tokens with the trade-offs of being less secure and, in the case that the blacklist app is being used, less performant. A sliding token is one which contains both an expiration claim and a refresh expiration claim. As long as the timestamp in a sliding token’s expiration claim has not passed, it can be used to prove authentication. Additionally, as long as the timestamp in its refresh expiration claim has not passed, it may also be submitted to a refresh view to get another copy of itself with a renewed expiration claim.
If you want to use sliding tokens, change the
AUTH_TOKEN_CLASSES setting to
('rest_framework_simplejwt.tokens.SlidingToken',). (Alternatively, the
AUTH_TOKEN_CLASSES setting may include dot paths to both the
SlidingToken token classes in the
rest_framework_simplejwt.tokens module if you want to allow both token
types to be used for authentication.)
Also, include urls for the sliding token specific
TokenRefreshSlidingView views alongside or in place of urls for the
access token specific
from rest_framework_simplejwt.views import ( TokenObtainSlidingView, TokenRefreshSlidingView, ) urlpatterns = [ ... path('api/token/', TokenObtainSlidingView.as_view(), name='token_obtain'), path('api/token/refresh/', TokenRefreshSlidingView.as_view(), name='token_refresh'), ... ]
Be aware that, if you are using the blacklist app, Simple JWT will validate all sliding tokens against the blacklist for each authenticated request. This will reduce the performance of authenticated API views.
