Your best authority synonym could be power, control, jurisdiction, permission or expert, because authority covers five ideas at once: the right to decide, the paper that grants that right, the officials who hold it, the person who knows the most, and plain credibility.
Under each heading below sits another word for authority, one sense at a time. The plural, the authorities, gets its own notes, since it nearly always means police or government.

Soft influence to total dominion
The chip strip measures how much someone can make others act. Influence persuades but cannot order. Having a say means your vote counts. Control means you run the thing day to day. Command adds rank, as in the military. Dominion is total rule over land or people and sounds old and grand.
Workplace writing usually needs the middle: a manager has control of the budget, not dominion over the team.
Choosing an authority synonym for school, work and law
Essays on politics or history: power, rule, sovereignty and legitimacy sound exact. Legitimacy is the right word when the question is whether the authority is accepted.
Office emails: sign-off, approval and say are friendly. Who has sign-off on this budget is clearer than who has authority over it.
Contracts and policies: authorization, mandate and jurisdiction are the precise terms. Do not swap them for casual words.
The authorities: what to say instead
In the plural, the word refers to officials, usually police, regulators or the government. Name them if you can, because a specific noun is clearer.
- The authorities are investigating becomes police are investigating.
- Report it to the authorities becomes report it to the city council or report it to the regulator.
- Local authorities in British English means local councils, so local government is the neutral swap.
Authority swapped out in context
- She has authority over hiring becomes she has the final say on hiring.
- Do you have the authority to sign this becomes are you authorized to sign this.
- He is an authority on old maps becomes he is an expert on old maps.
- Speak with authority becomes speak with confidence or speak with conviction.
- The agency lost its authority becomes the agency lost its credibility.
A team lead writes: "I do not have the authority to approve leave." A softer, clearer version: "Leave approval sits with HR, so I will pass your request to them." The reader learns who can help, not just who cannot.
Close cousins that are not quite synonyms
Leadership is guiding people; you can lead without formal authority. See leadership synonyms. Responsibility is duty, not power: you can be responsible for a result you have no authority to change. Force is the use of physical power, which authority may or may not involve. Expertise is the knowledge itself, while an authority is the person who has it.
Opposites of authority
For power, the opposites are powerlessness, weakness and subordination, the state of being under someone else. For the expert sense, the opposites are novice, amateur and layperson. Anarchy is the absence of any ruling authority, a word best kept for whole societies rather than a messy meeting.
