2048—If your domain provider supports 2048-bit keys, select this option. Longer keys are more secure than shorter keys. If you previously used a 1024-bit key, you can switch to a 2048-bit key if your domain provider supports them. Read more about domain keys and TXT record limits.1024—If your domain host doesn't support 2048-bit keys, select this option.
If your domain already uses a DKIM key with the prefix google, enter a different prefix in this field. Read more about DKIM selectors.
