Embed token expiration time concern

[lwgoBiadmin]

Hi All,

We are planning to cache token using redis, our concern is explained below.

     After generating the first token it will be stored in the cache and we will be using the same embed token until it expires.

     Scenario:   what if the report user access the report couple of minutes prior to the expiration of token and continue using the report after the expiration time. Will this intrupt them? Like displaying error messages.

Eg: the first token generated at 10am (suppose token expiration is 24 hours) and after 23.55 hours later again the report is accessed with the same token. The user continues to use the report after 24 hours.

Thanks

Hi @lwgoBiadmin ,

As far as I know, by default, the Azure token expiration time is one hour. There are two kind of embedding methods, embed for organization(user owns data)  and embed for customer (app owns data). 

Embed token should be used in app owns data. Power BI will generate embed tokens by Azure token generated by master account or service principal.

For reference: Understand the permission tokens needed for embedding a Power BI application

If you get report before your token expired, you may still could see your report by cache. However, if you do some interaction on your report, your report will be broken due to token is expired. Then you need to get active embed token.

Hi @v-rzhou-msft.,

Thanks for the reply.

Currently we are generating embed tokens by Azure token generated by service principal and by using a policy in azure we are able to increase the expiration time to 24hrs. Now we are checking expiration time and  generating token 30 minutes before expiration time. So that will solve this problem.
