Posted on by Community Power Pla... Microsoft Employee

Hi Experts,

I am having one Power Portal running and we are using Local Authentication. So, all the users who register them self are created in Contacts entity.

So, Basically I have one canvas app from where some other task is performed on Contacts Entity and wanted to add one more functionality i.e change the password of selected contact from the gallery.

How can I change the password of Contact from the canvas app? can we do that by calling automate flow or any script available by which we can change the password?

I can see Password Hash field in Contacts entity but if I update that field for a selected contact then that user is not able to log in from Portal and giving below error:
Password change issue from canvas app

Please help me with this. Any help will be appreciable.

Thanks,

Amit

You cannot dirctly update the password hash and have it work.
See the same question asked by someone else: https://powerusers.microsoft.com/t5/Building-Power-Apps/How-to-Encrypt-and-decrypt-password-field-of-contact-entity/m-p/633529#M200893

TL;DR you should not use local authentication--it is deprecated. But if you need to, you need to use a plugin to update it.

Hi @Anonymous ,

Do you want to update the password for the selected contact in a Gallery using canvas app?

If you want to update the password for the selected contact in a Gallery using canvas app, I afraid that there is no way to achieve your needs.

Actually, the password of a Contact record in your Portal would be hashed and stored in the adx_identity_passwordhash field on the Contact Entity. And Portal uses ASP.NET Identity (v2) for local authentication, and so leverages its default password hashing functionality.

Please check the following article for more details:

https://community.dynamics.com/crm/f/microsoft-dynamics-crm-forum/283515/the-portal-user-s-password-encryption-type/811085

So if you want to change the password for a selected Contact, you should convert your Text Password value into corresponding Hash value, then store it into your Contact Entity. But currently in PowerApps, there is no way to convert a Text value into a Hash value.

If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:

https://powerusers.microsoft.com/t5/Power-Apps-Ideas/idb-p/PowerAppsIdeas

In addition, when you sign in Portal using your local authentication, it would convert the typed password into a Hash value firstly, then compare the Hash value with the stored Hash value in your Contact Entity, if matches, validate successfully, otherwise, validate fail.

Best regards,

@Anonymous My suggestion of a plug-in was to have another field located somewhere else like a custom entity, which you could create a record with the non hash value, then have a plugin update the password with the hash format

@v-xida-msft is correct that you can’t directly update the password field, but if you can capture the value there are ways of having it converted to hashcode

thatbis covered on my original link
