I disagree, it's not about notifying the app, it's about getting a new token.

Wait, so they don't reset the app's config? That's surprising!

Refresh tokens are used to get new access tokens without re-authenticating.

I thought they just extended the access token's life?

Jonell 11 months ago

Definitely B, that's how it works!

I’m a bit confused about this. I thought refresh tokens were just for notifying the app that a new access token is needed, but that seems too simple.

Barrett 11 months ago

I feel like I came across a similar question in practice exams, and I think refresh tokens are definitely not about resetting configurations.

Edelmira 11 months ago

I think refresh tokens are used to get a new access token when the old one expires. It sounds like option B might be the right choice.

I remember studying refresh tokens, but I'm not entirely sure if they just extend the access token or if they actually replace it.

I'm pretty confident I know the answer to this one. Refresh tokens are used to request a new access token from the server when the old one expires, so that the user doesn't have to log in again. Option B seems to be the correct answer.

I'm a bit confused by the options here. I know refresh tokens are used to get new access tokens, but I'm not sure if that's the same as resetting the expiration time. I'll have to review my notes on this.

Okay, I've got this. The purpose of a refresh token is to extend the lifetime of an access token by resetting its expiration time. That way, the user doesn't have to log in again when the access token expires.

I'm a little unsure about this one. I know refresh tokens are used for authentication, but I'm not sure of the exact purpose. I'll have to think it through carefully.

Hmm, this one seems pretty straightforward. I think the purpose of a refresh token is to request a new access token when the old one expires.

Wait, so refresh tokens are like the superheroes of the token world, saving the day when access tokens expire? Cool!

Option D is just plain wrong. Refresh tokens don't notify the app that a new access token is needed - they're used to actually get that new token!

Kallie 1 year ago

I'm with Stefany on this one. Refresh tokens are all about getting a new access token, not extending the current one.

Option B sounds about right. Refresh tokens are used to request a new access token when the old one is no longer valid.

Monte 1 year ago

Haha, option C is a bit of a joke. Resetting an application to its default config? That's not what refresh tokens are for!
