# How To Sign Into Affinity
> Help center reference: How To Sign Into Affinity
**How-to** — task-oriented recipe.
Welcome to Affinity! In this article, we'll go over how to make sure you sign in correctly as a **user** or as a **collaborator**:
* **Users** have full read-and-edit access to the Affinity account, including [Directories](/s/article/All-people-and-all-organizations), [List](/s/article/Lists), [Profiles](/s/article/Navigating-profile-pages-in-Affinity), etc.
* **Collaborators** only have read-only access to [specific sheet views](/s/article/How-to-create-and-use-saved-views-in-new-lists) within Affinity lists.
* Team members **cannot** be invited as Collaborators, they must be invited as Users.
## Signing into Affinity for the first time
## Option 1: Signing in as a User
If you're signing into Affinity for the first time as a **user**, please follow these steps:
1. Click on the email invite that was sent to you, then click the **Join \_\_\_\_\_'s account** button.
2. Then, click **I am a user**.
3. Depending on which email provider your email account is based off of, select one of the articles below:

4. Please note that you can only sign into Affinity if your email provider is Gmail or Microsoft (i.e. Office 365, Hotmail, Live, etc.). You **cannot** sign into Affinity if your email account is from Yahoo, AOL, or any other email provider.
## Option 2: Signing in as a Collaborator
If you're signing into Affinity for the first time as a **collaborator**, please follow these steps:
1. Click on the email invite that was sent to you by the Affinity user, then click **Join Affinity**.
2. Then, click **I am a collaborator**.
3. If the Affinity user's company does **not** require you to sign in via SSO, then you can simply enter your email and click **Send Email**.
1. You will receive an email that contains the unique **Sign Me In** button that will verify your email address and sign you in as a collaborator.
4. If the Affinity user's company requires you to also sign in via SSO, please make sure they add you to their SSO provider's list. Once doing so, you will notice a different sign in option (e.g. **Sign in with OKTA**).
## Signing into Affinity moving forward
1. To sign into Affinity moving forward as a **user** or a **collaborator**, we highly suggest saving your unique Affinity subdomain as a bookmark on your web browser - it should be in the following format: `[subdomain].affinity.co`
2. If you're not sure what your Affinity subdomain is, please check out [How to find your Affinity subdomain](/s/article/How-to-find-your-Affinity-subdomain).
