All large brokerages are SIPC protected. The $500K coverage is for each separate capacity - individual, joint, retirement etc... We don't keep at separate brokerages because we like everything to be consolidated so that it is easier for the estate when we pass away. Link here:

Investors with Multiple Accounts
SIPC protection of customers with multiple accounts is determined by "separate capacity." Each separate capacity is protected up to $500,000 for securities and cash (including a $250,000 limit for cash only). Accounts held in the same capacity are combined for purposes of the SIPC protection limits.
Examples of separate capacities are:
individual account;
joint account;
an account for a corporation;
an account for a trust created under state law;
an individual retirement account;
a Roth individual retirement account;
an account held by an executor for an estate; and
an account held by a guardian for a ward or minor.
Additional information on separate accounts may be found in SIPC's Series 100 Rules.
The following are examples of separate accounts:
Mary has an account in her name at her brokerage firm. Mary is protected by SIPC up to $500,000.
Joe has two brokerage accounts, each in his own name. For purposes of SIPC protection, Joe’s accounts are combined, and Joe is protected by SIPC only up to a total of $500,000.
Joe and Mary are married and they have a joint brokerage account which is separate from the individual accounts that they each have at the firm. An additional maximum of $500,000 of SIPC protection is available for the joint account.
Joe has a Roth account and an IRA account, at the same brokerage. Joe is protected up to $500,000 for the Roth account and up to $500,000 for his IRA account.
