It doesn't really matter as long as you always use the same account. You can log into Gearset with an existing Salesforce, Google, or LinkedIn account, or with an email address and password.
The account you use to log into Gearset is only used to create your Gearset user profile. If you log in using a Salesforce account, we won't deploy to this org or read the metadata from it (unless you separately add it as an org connection). If you log in with a Salesforce, Google, or LinkedIn account, we don't see or store your credentials. They're held by that provider and managed through OAuth.
Pick an account you're likely to remember using, and one that won't be deleted. You'll use this account every time you want to log into Gearset.
If you accidentally log into Gearset using a different account, let us know. We will deactivate it for you so you don't end up with multiple accounts running in parallel.
Note when using sandboxes: when Salesforce sandbox orgs are refreshed, your Salesforce user account is sometimes deleted and recreated. This can mean you'll lose access to your previous history in Gearset, as your Gearset account is tied to a specific Salesforce user. We recommend you don't use sandboxes for paid Gearset subscriptions. You may want to use the guide to change your login.
Can I log in with an email address and password?
Yes. You can create a Gearset account with an email address and a password instead of using an OAuth provider.
Email and password accounts can't join a team that was created with an OAuth or SAML method until a team owner allows them. A team owner turns on the Email and Password option from the Team Management settings page. For the steps, see Restricting how users can accept invitations to join your team.
