Account access

Select Login to contribute, vote, comment, or participate in a study. The vocabulary and documentation are public. Use the same account as before to keep your contributions and memberships together.

Begin sign-in from the study page to return there afterward. Existing members can also find studies under Your studies on their profile. Select Join and begin study when it appears. Otherwise, contact the person who shared the link if access is required. See Studies.

Verified email sign-in

Enter the email address attached to your account and select Email me a sign-in link. Open the short-lived, one-time link to sign in without a password. The confirmation looks the same whether or not the address matches an account. Public profiles omit email addresses.

Create an account with email

Use Create an account with email for a new account when that form is available. Follow the email link, then complete your name and profile choices. An invitation or study destination is retained through this process, including when you open the email link in another browser or device.

Sign in to your existing account if you already contributed. A second account has separate contributions and memberships. Contact the person who invited you if no available method lets you create an account.

Continue with Google

Select Continue with Google and choose your usual Google account. A new contributor completes their profile before returning to a pending study or invitation. Check the selected Google account if access is refused, then contact the person who invited you if the problem continues.

ORCID

An ORCID iD identifies a researcher. Connect one through the profile editor when ORCID access is enabled. A connected iD can also be used to sign in. Each iD belongs to one MatSci-SAM account. It cannot create or merge accounts through sign-in alone.

You can disconnect the iD after verifying another sign-in method. Contributions retain their account attribution. Public ORCID display follows the profile visibility setting.

Trouble signing in

• Check spam and the email address if no sign-in message arrives. The sign-in form requires an existing account. Request another link after the waiting period shown on the page.
• Request a new link if the previous one expired or was used. Open the most recent message.
• Check your account if studies or contributions are missing. Memberships and activity belong to the account used to create them.
