How to get user id client-side

how to install the python backend with pip?

Hey, I have a hard time understanding how to use supertokens. All the user data is stored in one database (MySQL) and all my other data, for example lists that the user creates are stored in another database (MongoDB). How can I connect them?

Hey @rp_st we want to authenticate whether the client redirect URL is correct or not, if it is correct, then only we want to generate the accesstoken 1.can you show us is it possible or not? if yes, how? 2. does the supertoken store the client redirect url or not in their system? and if they do, what is the method from nodejs-sdk to verify the client redirect url?

Can we give access to multiple email IDs for same supertokens account? One of my colleagues created the account, but is unable to give me access to it.

When self-hosting, is there a good reason why not to run the core on the same server as the backend? I'm using a DigitalOcean droplet which will run my app backend, supertokens backend and I'm thinking why not run the core there too?

Hello again! Another question: [The Adding fields page from the docs](https://supertokens.com/docs/emailpassword/common-customizations/signup-form/adding-fields) says that it's possible to include extra fields on sign-up (such as display name, location, or age), but then at the very end of the page, it says: "SuperTokens does not store custom form fields. You need to store them in your db post user sign up." When the

signUp

function is called in step 1, where does the

name

,

age

, and

country

go when a user signs up? I'm curious because I want to include an optional display name field in my sign-up form. I can implement storing the extra field (associated with either the user's email or ID) in my own database, but I'm confused as to why adding the field to the configuration is necessary since SuperTokens can't store the field. Thanks again in advance!

Hey, I have a question about the website domain with multipe frontends. Refering to the docs:

On the backend, you should set the websiteDomain to be your main domain (example.com if your sub domains are sub.example.com), and then you want to override the sendEmail functions to change the domain of the link dynamically based on the tenant ID supplied to the sendEmail function. See the Email Delivery section in our docs for how to override the sendEmail function.

for what is this websiteDomain used for? I have the following domain setup: a.domainA.com -> uses api.domainA.com b.domainA.com -> uses api.domainA.com so i should set websiteDomain to domainA.com. But i have another frontend: domaniB.com -> used api.domainA.com what to do now here?

Hi, I'm getting an error when trying to follow the instructions for Third Party Email Password, but I keep getting this error :

No instance of ThirdPartyEmailPassword found.

hi guys, quick question. Using listUsersByAccountInfo method to get user(filtering by tenantId and email). Our set up means that 2 users(EmailPassword and Passwordless) are returned. is there an easy way to retrieve just the EmailPassword user? Worth adding that we dont use account linking
